I'm using windows vista and starting yesterday, every time I try to open something other than internet explorer, a box pops up saying autmgr32.exe has stopped working. I tried running Malwarebytes Anti Malware software in safe mode, but the same dialogue box pops up and says that autmgr32.exe stopped working. I also renamed the mbam.exe file to see if that would work, but it didn't.
(There is also something about troj/agent-nsu. I have no idea what that means either, but another dialogue box keeps popping up about that.)
How do I solve this? Do I have some sort of virus?
