  • Problems using InfraRecorder to back up ISOs of certain CDs

    - by Voyagerfan5761
    I've gotten into the habit of backing up my CDs as ISO files, just in case the discs should be damanged, lost, or destroyed. Using InfraRecorder, the process is pretty painless. Unfortunately, I have run into at least two discs that don't back up. I get the error message: Can't read source disc. Retrying from sector 252270 Sometimes this will appear repeatedly. One of the discs is my retail copy of Star Trek: Armada II; the other is disc one of DOOM 3. Both discs run flawlessly when I put them in the drive and let Windows AutoPlay them. Armada II appears as two tracks (one data, one audio) in InfraRecorder, and the error happens at the approximate track boundary. DOOM 3's first disc, however, fails much sooner (around sector 990) and appears as one solid data track. Am I simply using the wrong tools for this job? InfraRecorder is a nice free tool that I can run from my flash drive and use for most tasks of this type, but it does seem to have trouble with certain things. Ideally I'd like to hear about any workarounds people have found for this issue, but if I must switch tools I'm open to it (preferably other free tools).

  • 2011 i7 Macbook Pro unable to boot from any Windows CD?

    - by Craig Otis
    I'm encountering issues installing Windows alongside my Lion install. I'm attempting to install from the internal SuperDrive, after using Boot Camp to partition what was a single, HFS+ volume. When holding down Option at boot, the CD appears in the startup list, but upon selecting it, I get a gray screen for 5 minutes, then a flashing white folder. I tried installing rEFIt and using this to boot the CD, but I receive an error about "Not Found" being returned from the "LocateDevicePath", and a mention of the firmware not supporting booting using legacy methods. In the Console, when opening the StartupDisk preference pane (which never presents the CD as a selectable option), I see: 11/25/11 4:39:31.159 PM System Preferences: isCDROM: 0 isDVDROM:1 11/25/11 4:39:31.159 PM System Preferences: mountable disk appeared: /Volumes/GRMCPRFRER_EN_DVD 11/25/11 4:39:33.214 PM System Preferences: - So far so good, passing disk to System Searcher. 11/25/11 4:39:33.218 PM System Preferences: OSXCheck: No boot.efi in System Folder or volume root. 11/25/11 4:39:33.220 PM System Preferences: WinCheck: Not a valid windows filesystem: /Volumes/GRMCPRFRER_EN_DVD 11/25/11 4:39:33.220 PM System Preferences: WinCheck: Not a valid windows filesystem: /Volumes/GRMCPRFRER_EN_DVD I'm at a loss here. I've done my research, but it sounds like most of the rEFIt errors of this nature are caused by installing from a thumbdrive, or an external drive. I'm using the internal SuperDrive. Also, I've tried this with two different disks: A Windows XP SP2 CD A Windows 7 x86 DVD Both are disks I've had around for years, and I've used them reliably in the past. The system is an early 2011 15" Macbook Pro, all firmware updates installed.

  • Handling the Outlook 2007 AutoArchive PST file

    - by Doug Luxem
    We encourage our users to enable AutoArchive in Outlook 2007 as a way to manage their mailbox sizes. However, we frequently end up running in to problems with the archive.pst file that is generated. The two main problems we have are: The archive.pst file is located in the user's local profile directory and is never backed up. A dead hard drive or stolen laptop could result in months or years of missing email. All other personal data is stored on network shares, but we can't do that for Outlook PST files. Without some sort of manual intervention, the archive will grow to enormous sizes. Although Outlook 2007 SP2 handles the large files better than before, it still results in slow response times from Outlook and an increase likelihood of a corrupt PST file. To mitigate these problems personally, I move the archives to a c:\Outlook folder and manually back that up to a shared drive every month or so. Additionally, I rotate archive files every year so that I have one file for each year (archive2008.pst, etc). Obviously, asking our users to do this same wouldn't help much. We need some sort of automated solution to take care of points 1 and 2. I have to imagine this is a common problem for Exchange organizations, so what is the best method to handle this?

  • Home Server: storage virtualisation, what to choose?

    - by Huygens
    I'm looking for virtualisation solutions for storage and OS for a home server. A sort of private cloud where I manage the storage space independently of the VM one. This question focus on storage management. (I have another question related to the VM/compute instance management). Here my environement and wishes. Server: HP Proliant MicroServer with 8 GB RAM (AMD Turion dual core with AMD-V technology) with 1 250GB system disk and up to 4 HDD (2 TB) for "data" OS types: only Linux (perhaps a *BSD VM in the future) Linux distributions do not matter, I'm familiar with RHEL, Fedora, Suse, Ubuntu, but any other recommandation will be fine The 4 HDD is going to be a software RAID array, probably RAID 5. storage should be "virtualised/cloudified": easy to extend: if I add a NAS on the network, I can include the NAS space capacity within this storage space as one virtual disk. This can be a NAS, an external HDD or another server. cluster FS or S3 style space or OpenStack block storage? Whatever is easier to manage/maintain and easy to integrate/plug to VM/compute instance. I would prefer free (libre, as in a free speach) and open source tools. But it does not have to be free as in a free beer. Note: the VMs I intend to run on top of this server are one dedicated to backup, one for a "owncloud/dropbox"-like service and perhaps one for media server (hosting video and photos). I'm not sure if traditional VMs or compute instance are the most suitable for this.

  • My Computer hangs for a few minutes just after startup, and then is fine.

    - by EvilChookie
    So I just built myself a reasonably beefy computer, and I installed Windows 7 on it. However, I start the machine up each morning and within a few minutes, the computer will semi hang. That is the mouse is responsive, and most of the time I can open task manager, or a new tab in Chrome. Occasionally windows will be labelled as 'Not responding'. Then, the machine will get over it's problem, and will be nice and quick until I turn it off. Here's my specs: CPU: AMD Phenom-II X4 955 Black (Quad Core, 3.2ghz) RAM: 4GB of DDR3 1300 MOBO: ASUS M4A785T-M (Latest BIOS) HARD DRIVES: 2x1TB Western Digital Caviar Blacks in RAID-0. OS: Windows 7 Ultimate x64. GPU: ASUS GT240 1GB. I believe this issue relates to the RAID array, as I didn't have the lockup problem before I created the array. I purchased a second drive and reformatted after creating a RAID array, since the single drive was a little on the pokey side (compared to the rest of the computer). What I have tried: Updated Raid Drivers Malware checks Windows Updates Unecessary Services CPU and Disk activity appears to be low (via Resource Monitor) No strange errors in the error log. Any thoughts?

  • USB Harddisk not working on dual boot windows7/8

    - by Jesper
    Yesterday I installed Windows 8 on a machine that already had Windows 7. They are on dual boot and both systems work fine. The problem is that inserting a USB hard disk in either system does nothing. If I connect a USB mouse or mobile phone, they work fine, so the USB plugs are active/working and the USB hard drives that I am trying to connect work on my other laptop just fine. I have tried to uninstall all USB-related items in Device Manager and let them reinstall upon restart, but that didn't help. The USB drive does not show up in disk management either. The strange thing is that it is exactly the same situation on both windows. USB mice etc. work just fine and USB hard drives do not. Any ideas on solving this problem would be great. ...Don't know if it is important, but this is a Toshiba Tecra R950 Laptop. EDIT: I have found out that my other USB HD (Western Digital) works on this laptop, but for my StoreJet Transcend and Adata "something" does not work. All three work on another Windows 7 laptop. Sizewise the WD is in the middle at 400 GB. The StoreJet is 640 GB and the Adata is 200 GB.

  • Allignment of ext3 partition on LVM RAID volume group

    - by John P
    I'm trying to add a partition on a LVM that resides on a RAID6 volume group and fdisk is complaining about the partition not residing on a physical sector boundry. My question is, how do you calculate the correct starting sector for a partition on a LVM? This partition will be formated ext3. Would it be better to just format the LVM directly instead of creating a new partition?

  • I cannot access Windows Update at all

    - by Cardinal fang
    I have been unable to access the Windows update site for a couple of weeks now. I just get a message saying "Internet Explorer cannot display the webpage" and saying I have connection problems. Same thing is replicated with any other Microsoft site I try to access. The Automatic Updates also do not work. I can access every other wesbite I've surfed to. I've tried Googling the problem and based on what other site have suggested I have cleared my cache and temp files. I've scanning my hard drive with my antivirus in case I have a virus (nada). I've tried turning off my firewall and anti-virus (I run Zone Alarm). I've downloaded SpyBot and scanned my drive with that in case something was missed by Zone Alarm (again nada). Based on suggestions from the smart cookies on the Bad Science forum, I've used nslookup to check my translation isn't wonky (got all the info they said I should get). I've also tried navigating there directly using the IP address I was given (nope). I normally access the internet through a 3 mobile broadband connection, but have also tried connecting using a mate's wi-fi connection in case it was something on my mobile modem interferring. I run Windows XP SP3 with Internet Explorer 7 and Zone Alarm Internet Security Suite as my anti-virus/ firewall. Any suggestions?

  • File Replication Service Errors

    - by ekamtaj
    Hey Guys, We have a windows 2003 r2 server and couple of the users are reporting that they can not scan files into the windwos server. They are getting an Out of Space errors. I took a look at the server and we have 600GB free disk space on that partition. But while looking at the event log I found a lot of errors like (13552,13555) The File Replication Service is unable to add this computer to the following replica set: "DOMAIN SYSTEM VOLUME (SYSVOL SHARE)" This could be caused by a number of problems such as: -- an invalid root path, -- a missing directory, -- a missing disk volume, -- a file system on the volume that does not support NTFS 5.0 The information below may help to resolve the problem: Computer DNS name is "server.domain.local" Replica set member name is "server" Replica set root path is "c:\windows\sysvol\domain" Replica staging directory path is "c:\windows\sysvol\staging\domain" Replica working directory path is "c:\windows\ntfrs\jet" Windows error status code is FRS error status code is FrsErrorMismatchedJournalId Other event log messages may also help determine the problem. Correct the problem and the service will attempt to restart replication automatically at a later time. For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

  • Windows Photo Viewer can't open this picture because you don't have the correct permissions to access the file location

    - by Software Monkey
    My system in Windows 7 and fully up to date with all patches and options (except for Microsoft Silverlight, which I refuse to install). I get this error whenever I try to open an image using Windows Photo Viewer, such as when previewing from Explorer or when opening an image attachment to an email. I have already verified correct permissions to the file and all folders in the path. The strange thing is that every other program I have seems to open the images fine, including "Slideshow" from Windows Explorer. Even more strange, in WPV there is an "Open" menu that lists the other programs for images including GIMP and MS Paint and they open the very file that WPV is complaining about just fine. That should eliminate permissions as being the problem, especially since (logically at least) they are read/write while WPV is read-only. I have even edited and saved the images that WPV does not open. I am out of ideas, and searching for answer on the Web has resulted only in the same tired repitition of some flavor of "take ownership and reset permissions for the entire drive", which I have already done. And which is counter-indicated by the fact that only Windows Photo Viewer seems to have a problem. The one thing which is slightly unusual is that for normal files they are all on a second HDD mounted into C:, however for email attachments the temporary folder is C:\Temp\, which is directly on that drive.

  • Is my OCZ SSD aligned correctly? (Linux)

    - by Barney Gumble
    I have an OCZ Agility 2 SSD with 40 GB of space. I use it as a system drive in Debian Linux (Squeeze) and in my opinion it's really fast. But I've read a lot on aligning partitions and file systems... And I'm not sure if I succeeded in aligning the partitions correctly. Maybe the SSD could be even faster?? ;-) I use ext4 and here is the output of fdisk -cul: Disk /dev/sda: 40.0 GB, 40018599936 bytes 255 heads, 63 sectors/track, 4865 cylinders, total 78161328 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: [...] Device Boot Start End Blocks Id System /dev/sda1 * 2048 73242623 36620288 83 Linux /dev/sda2 73244670 78159871 2457601 5 Extended /dev/sda5 73244672 78159871 2457600 82 Linux swap / Solaris My partitions were created just by the Debian Squeeze setup assistant. So I didn't care about the details of partitioning. But now I think maybe the installer didn't align it correctly? Actually, 2048 looks good to me (better than odd values like 63 or something like that) but I've no idea... ;-) Help plz! According to some "SSD Alignment Calculator" I found on the web, the OCZ SSDs have a NAND Erase Block Size of 512kB and their NAND Page Size is 4kB. 2048 is divisible by 4 and 512. So are the partitions aligned correctly?

  • Hyper-V vss-writer not making current copies

    - by Martinnj
    I'm using diskshadow to backup live Hyper-V machines on a Windows 2008 server. The backup consists of 3 scripts, the first will create the shadow copies and expose them, the second uses robocopy to copy them to a remote location and the third unexposes the shadow copies again. The first script – the one that runs correctly but fails to do what it's supposed to: # DiskShadow script file to backup VM from a Hyper-V host # First, delete any shadow copies of the drives. System Drives needs to be included. Delete Shadows volume C: Delete Shadows volume D: Delete Shadows volume E: #Ensure that shadow copies will persist after DiskShadow has run set context persistent # make sure the path already exists set verbose on begin backup add volume D: alias VirtualDisk add volume C: alias SystemDrive # verify the "Microsoft Hyper-V VSS Writer" writer will be included in the snapshot # NOTE: The writer GUID is exclusive for this install/machine, must be changed on other machines! writer verify {66841cd4-6ded-4f4b-8f17-fd23f8ddc3de} create end backup # Backup is exposed as drive X: make sure your drive letter X is not in use Expose %VirtualDisk% X: Exit The next is just a robocopy and then an unexpose. Now, when I run the above script, I get no errors from it, except that the "BITS" writer has been excluded because none of its components are included. That's okay because I really only need the Hyper-V writer. Also I double checked the GUID for the writer, it's correct. During the time when the Hyper-V writer becomes active, 2 things will happen on the guest machines: The Debian/Linux machine will go to a saved state and restore when done, all fine. The Windows guests will "creating vss snapshop-sets" or something similar. Then X: gets exposed and I can copy the .vhd files over. The problem is, for some reason, the VHD files I get over seems to be old copies, they miss files, users and updates that are on the actual machines. I also tried putting the machines in a saved sate manually, didn't change the outcome. I hope someone here has an idea of how to solve this.

  • Linux Mint Constantly freezing on Dell XPS L502X

    - by Josh
    I recently partitioned my hard drive to dual boot the existing Windows 7 with Linux Mint because I am tired of using Windows, especially the lack of terminal. I want to eventually remove Windows 7 and just run it from a VM within Linux Mint, but I want to make sure that I like the Mint before going all in. I ran Linux Mint on a VM inside Windows for a while, enjoyed it, and never had any issues with it. Since installing on my hard drive it has started freezing every 5-10 minutes, and the only way to get it back is to either power down, or close the lid and reopen once it sleeps. I've also tried running Ubuntu on dual boot in the past, and while it never froze, the battery life was terrible, and the fan was constantly running. I'm experiencing the same battery/fan problem with Mint, which doesn't make sense to me, as Linux should be lighter on the CPU than windows. If I had to guess I'd say it's probably a driver thing, with my video card or fan or something. My battery life in Windows is ~2 hours and its about 40 minutes in Linux. At this point, that is even if my laptop doesn't freeze before then. On a less important note, I also have an intel Centrino 6150 WiMax card that I'd like to be able to use, but that won't register on the Linux system either. I have tried downloading drivers for both of these, but neither have solved my problems. I'm definitely getting frustrated and am getting close to giving up on Linux even though I dread working on a Windows machine.

  • Is execution of sync(8) still required before shutting down linux?

    - by Amos Shapira
    I still see people recommend use of "sync; sync; sync; sleep 30; halt" incantations when talking about shutting down or rebooting Linux. I've been running Linux since its inception and although this was the recommended procedure in the BSD 4.2/4.3 and SunOS 4 days, I can't recall that I had to do that for at least the last ten years, during which I probably went through shutdown/reboot of Linux maybe thousands of times. I suspect that this is an anachronism since the days that the kernel couldn't unmount and sync the root filesystem and other critical filesystems required even during single-user mode (e.g. /tmp), and therefore it was necessary to tell it explicitly to flush as much data as it can to disk. These days, without finding the relevant code in the kernel source yet (digging through http://lxr.linux.no and google), I suspect that the kernel is smart enough to cleanly unmount even the root filesystem and the filesystem is smart enough to effectively do a sync(2) before unmounting itself during a normal "shutdown"/"reboot"/"poweorff". The "sync; sync; sync" is only necessary in extreme cases where the filesystem won't unmount cleanly (e.g. physical disk failure) or the system is in a state that only forcing a direct reboot(8) will get it out of its freeze (e.g. the load is too high to let it schedule the shutdown command). I also never do the "sync" procedure before unmounting removable devices, and never hit a problem. Another example - Xen allows the DomU to be sent a "shutdown" command from the Dom0, this is considered a "clean shutdown" without anyone having to login and type the magical "sync; sync; sync" first. Am I right or was I lucky for a few thousands of system shutdowns?

  • Windows 7 Professional Cannot Connect to Share - Wrong password

    - by henryford
    I know that this question has actually been asked a few times before, but every solution I found didn't yield any results on my end, I can't get my head around it: When I am trying to connect to a share on the network, I always get the response "The specified network password is incorrect". However, the password is definetly correct and it works if I connect from another machine. I changed the LAN Manager authentication level to "Send LM & NTLM - use NTLMv2 session security if negiotated", I configured Kerberos encryption types to include all suites, rebooted (several times), but still - no luck. I can connect if I use my regular account with which I am logged in, but I need to connect with a different user since my log-in user has not enough privileges on the share. When I do that, the error above comes up. I'm really frustrated at the moment, this problem is driving me crazy. I'd be gladful for any possible solution to this. At the moment I'm using a workaround: I connect to a different machine via RDP, login with the user I have to use for the network-share connection and then I can map the drive and copy/paste from the RDP session to my local workstation. This is also working when I am connecting via RDP with my current login user and map the drive with the other user who has sufficent privileges. Tanks in advance, Thomas

  • What is the proper way of debugging a slow Windows installation?

    - by Niklas
    You know the drill - you've been asked to check why you cousin's computer is running slow. I was there yesterday. Being a Mac user since 2007 I haven't really dug deep in Windows internals in the past five years. Googling for answers reveals many, many different answers: broken registry, spyware, antivirus program, fragmented disk, turning of visual effects etc. In this particular case I was asked to look at a two year old HP laptop with Vista. Windows was running incredibly slow and even opening up a new explorer window took almost a minute. I ended up doing everything of the above: running cc cleaner, defragmenting the disk, turning off visual effects, turning off norton and a bunch of other things people believe have an impact on Windows performance. Now I'd like to understand this in depth. Is there a proper, "scientific" if you so will, way of debugging and understanding where the problem with a slow running Windows installation lies? (In my particular case this concerned Windows Vista but let's try to create general guide for XP and Windows 7 too). To me, it seems wrong to just run a bunch of different tools without understanding the underlying cause of the error.

  • How to force mdadm to stop RAID5 array?

  • How to get rid of "Maxback Engine" for good?

    - by Jonik
    I used to have a Maxtor Shared Storage II network drive; it broke down long ago already. (Later I tried to recover some data from it, and partially succeeded, but haven't yet fully documented it on that question.) Anyway, I just noticed there are still some lingering bits remaining of the (thourougly crappy) software that came with the Maxtor device: a background process called "MaxBack Engine". I googled around a bit and found something related but not very useful: http://www.straitmac.com/jforum/posts/list/600.page http://discussions.apple.com/thread.jspa?threadID=725692 Under /Applications I found "Maxtor EasyManage.app" which I used to use for controlling the drive, and showed it some "rm -rf". Before deleting, I noted that the bundle did contain "MaxBack Engine.app" under Content/Resources. But still, after reboot, the "MaxBack Engine" process is back. I did notice though that it only appears when logging in with my usual user account; with another account it wasn't launched. So, dear Mac gurus, what could I do about this pest? I guess I could fall back to some Unix hackery and write a cronjob that kills any process with that name, but obviously it'd be nicer to be able to clean up from my computer everything left behind by Maxtor's piece of software.

  • How to reinstall bootloader after migration to SSD

    - by hijarian
    I must say, it was difficult to name this question. Basically, I need to properly reinstall the bootloader on my system, because I already have the working system disks for my OSes. The long story is this: I had the large slow HDD with Windows7 & Debian Wheezy dual-boot on it, perfectly bootable. Then, I ordered the SSD drive and prepared my system partitions to fit onto the much smaller SSD. I wanted the following schema: 128 GB Windows 24 GB / on Debian 86 GB /home on Debian Strange size for /home because there's no such thing as true 256GB disk drive. So, I've prepared such a partitions on my initial HDD and installed the new SSD and then I loaded the GParted live USB (can't remember now how it was really named), and then just copypasted the partitions from HDD to SSD. So, now I have the following partitions across the physical disks: SSD 128 GB copy of original Windows partition 24 GB copy of presumably Debian / 86 GB copy of presumably Debian /home HDD 128 GB Windows 24 GB / on Debian 86 GB /home on Debian ... several other partitions with non-system data ... And the behavior of the system right after the Ctrl+C, Ctrl+V in GParted was as follows: no GRUB, system boots right into the Windows on HDD. In BIOS settings are to boot from SSD first. I managed to create the Debian Testing installation USB and loaded it into the rescue mode, found that it identified my SSD as /dev/sda and installed the GRUB to the /dev/sda. Now my system loads the GRUB which lists both Windows and Debian. From HDD. So, I am now back into initial position. Please, how I should set up the GRUB so it'll load the OSes correctly from SSD? Should I fire up my Debian, fiddle with the GRUB's config and reinstall it again to the same place (at SSD)?

  • How do I stop linux from trying to mount android phone as usb storage?

    - by user1160711
    When I plug in my Motorola Triumph to my fedora 17 linux box USB port, I get an endless series of errors on the linux box as it desperately attempts to mount the phone as a USB drive. Stuff like this: Jun 23 10:26:00 zooty kernel: [528926.714884] end_request: critical target error, dev sdg, sector 4 Jun 23 10:26:00 zooty kernel: [528926.715865] sd 16:0:0:1: [sdg] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE Jun 23 10:26:00 zooty kernel: [528926.715869] sd 16:0:0:1: [sdg] Sense Key : Illegal Request [current] Jun 23 10:26:00 zooty kernel: [528926.715872] sd 16:0:0:1: [sdg] Add. Sense: Invalid field in cdb Jun 23 10:26:00 zooty kernel: [528926.715876] sd 16:0:0:1: [sdg] CDB: Read(10): 28 20 00 00 00 00 00 00 04 00 If I go ahead and tell the phone to allow linux to mount the USB storage, the messages stop, and I get a mounted drive, but if all I want to do is use the debug bridge, my log on linux will continue to fill with this junk. Is there some udev magic I can do to make the system ignore this particular device as far as usb storage goes? I just noticed that if I tell the phone to enable USB storage, let linux recognize the new disk, then tell the phone to disable USB storage again, I get one additional log message about capacity changing to zero, but the endless spew of messages stops, so I guess one work around is to enable and disable USB right away.

  • Hibernate between OS X and Bootcamp Win 7

    - by Willem
    Wouldn't it be great if someone wrote a guide or an app which allowed you to switch instantly between OS X and Windows using Hibernate in both OS:s? Windows 7 already has an option "Hibernate" which allows you to boot back to your OS X partition, but OS X does not exactly offer the same. However, there are possibilities here. It seems that the recent Mac's have 3 different kinds of sleeping mode: Sleep: Low power consumption, RAM still active. Legacy Safe Sleep: No power consumption(?), writes RAM to disk and shuts down (is this the same as Hibernate?) Safe Sleep: Writes RAM to disk and enters sleep mode. If battery level drops too low it goes into Hibernate (is this Hibernate the same as #2 in this list? This is the Hibernate I will be referring to int he rest of this post) It seems that I am unable to force my MacBook Pro (Late 2011) OS X 10.7.3 into a true hibernate using either command line or apps that are supposed to do this. I believe the Mac should show that white loading bar whilst waking up if it was truly put into hibernate (which it does not). But I can get this white bar to show by letting my battery level drop to 0% so there is obviously a system function for it (obviously, duh! :). When Win 7 goes into hibernate it shuts down completely and you can then boot into OS X on startup. On OS X however, hibernate forces you to wake up into OS X. Can you hack this so that you're allowed to select boot partition after OS X hibernates? Would it be possible to use the true hibernate system functionalities of Win 7 and OS X to create a kind of instant switching between the two? Imagine this on a quick SATA-3 SSD like my 180GB Intel 520. Thanks / Willem

    Possible Duplicate: Computer is infected by a virus or a malware, what do I do now? [Note: This is not a duplicate and should not be closed as a duplicate as this is nothing like the other question. I am not asking if I have a virus, nor am I asking "what do I do now". I know that I have a virus and I know what to do. However, I am asking if these are normal AVG ads or if it has been taken over.] My Windows XP PC started acting strange and I am right now actually in Linux running off of a USB drive. I am running Avast under Linux and it has discovered some viruses on my XP drive. Some of the strange things happening in XP were: I could not get to Google.com My Hosts file was set to hidden and read only My Hosts file had an entry of ::1 And AVG had ads in it I've never seen before. Maybe it is normal but I Binged for AVG anti-virus and become.com but found no information. (The red lines and question mark are by me) Any thoughts?
