Hi,
Have a difficult virus problem, and would appreciate any help.
Started with a Google hijack - being sent other places when I clicked on google results.
Then became a problem where my mouse & keyboard (PS2 style) would lock up as soon as I try to use the keyboard.
Can use a USB mouse successfully; haven't tried a USB keyboard.
Ran several anti-virus programs - Panda, Avast, Ad-Aware... they found one or two problems, which they fixed, but google hijack & keyboard problems persist.
Ran through the process on your site, and have attached logs.
Running WinXP
Help would be much appreciated, thanks!!!

Found the solution, though it took a bit of searching to figure out.
Discovered that my kbdclass.sys driver, which runs the keyboard, had been corrupted. Standard virus removers took out the viruses, and I replaced the driver with a clean one from elsewhere, but that didn't repair the keyboard problem, which would lock up the PS2 keyboard & mouse as soon as you tried to use them after rebooting. Could get a USB mouse to work, so at least had access to the computer & on screen keyboard.

The problem turned out to be that the virus added a couple keyboard drivers, and changed registry entries. If you search the registry for kbdclass, some of the results have a field called "Upper Filters" (there may be more than 1 registry entry with this field). That field should contain only kbdclass. Anything else should be deleted (unless you know it's something specific to your setup & is supposed to be there), and just like that, the problem goes away.

Hope this helps someone thumbup2.gif

As this issue appears to be resolved I am closing the topic. Please send me (or any other Moderator) a Personal Message (PM) if you would like the topic re-opened.
