High CPU usage by 'svchost.exe' and 'coreServiceShell.exe'
- by kush.impetus
I am having a laptop running on Windows 7 Ultimate 32-bit. Since past few days, my laptop is facing a serious problem. Whenever I connect to Internet, either svchost.exe or coreServiceShell.exe or both hog the CPU. The coreServiceShell.exe consumes a lot of RAM also.
Going into the details, I found that high CPU usage of svchost.exe is caused by Network Location Awareness service.
And the high CPU usage of coreServiceShell.exe is caused by Trend Micro Titanium Internet Security 2012.
That kind'a makes me think that Trend Micro may be the root of the problem.
After further testing, I found that if I use IE or Firefox to browse the Internet, immediately after connecting to Internet, things are normal. See

But if I use Google Chrome, the coreServiceShell.exe hogs both CPU and RAM.
At this point, if I disconnect the Internet, the CPU and RAM usage by coreServiceShell.exe continues to be high till I close the Chrome. Also, when I close the Chrome, while Internet is connected, svchost.exe continues to hog CPU but coreServiceShell.exe leaves the race.
That makes think that Chrome is the root of the problem, but again, tracing coreServiceShell.exe takes me back to Trend Micro Internet Security. Stopping the Protection by the Trend Micro Internet Security doesn't help either (I am not able to stop its services though).
I have updated the Chrome, but no help.
I just can't figure out who is the culprit. I can't do without the Google Chrome (of course, by not using it) because of its immensely useful and indispensable features both during browsing and development. Secondly, I can't uninstall the Trend Micro Internet security Suite since it still has few months before it expires and is proving me reliable protection.
What could be the cause of the problem and what can I do to resolve this?
Thanks in advance
