Whenever I open the task manager, within a few seconds it crashes, saying it has stopped working with the above report.

I took the fault module (hostv32.dll) and scanned it with avast but it found no threat. I also ran a SFC /scannow from an elevated command prompt and it didn't find any corrupted files. This problem is in all two user accounts in this computer (Windows 7). Any reason/solution to this problem?

Avast isn't a very good scanner IMO. Try scanning it with 40 other scanners. (That sounded too much like a Russian software ad.) – digitxp Jan 3 '11 at 4:21
Does the same happen in safe mode? – John T Jan 3 '11 at 4:29
I'm going with you have a mean rootkit that does in memory patching or redirections of syscalls and it's causing taskmanger to puke. Boot from live media and scan from there(with better AV). – RobotHumans Jan 3 '11 at 5:43
