I have a Logitech Optical Mouse/Keyboard.

I have been using them just fine with the system drivers for almost a year now.

I recently updated my Kaspersky software and rebooted.

Now the mouse is frozen in the middle of my screen.

I am not able to login to the Windows XP Pro box that has the frozen mouse (because i can't work the mouse) but am able to remote desktop to this computer.

Things I know / have tried:

When I boot on the problem computer, I am able to use the keyboard, but not the mouse.

I have installed the latest version of Logitech's SetPoint (with the updated drivers) on the problem computer (via remote desktop) and that didn't seem to matter.

I bought new batteries for the mouse and that didn't matter.

I have tried the mouse/keyboard on another computer and the mouse works just fine there.

My suspicion is that the Kaspersky install has overwritten a driver of some sort.

Things I have not done (and would appreciate detailed steps if you feel this is the way to go):

1) Uninstalled all the mouse drivers on the machine and reboot. Then, reinstall.

Note: When I get to the Device Manager I don't see an option for Human Interface Devices (where the mouse device is). Here are my options: Computer, Disk Drives, DVD/CD-Rom drives, Floppy controllers, IDE ATA/ATAPI, Imaging devices, Network Adapters, Other devices, Ports, Processors, Sound, video, and gaming, System devices, USB controllers. Also, I should point out that Video Controller is the only thing under Other devices and it has a yellow exclamation mark. The same is true for all the items under Universal Serial Bus controllers. I think this means I have to update my BIOS but, since my mouse was working just fine without doing that, I don't think that is my problem. So, how do I get to my Mouse Device?

2) Update my BIOS.

Note: As pointed out above, I don't think this matters as my mouse was working just fine under my computer's current BIOS version.

Thanks for your help.
