I somehow got infected with Vundo.h When I run MBAM, it detects 8 infections and says it removed all except one (c:\windows\system32\silehoya.dll), which it says will be deleted on reboot. But after reboot it is back. And if I run MBAM again, it says there are still 8 infections.
Also when i reboot, I get a message that (c:\windows\system32\silehoya.dll) failed to load.
I also tried Spybot S&D, which also found several infections but could not remove them. McAfee and Trend Micro do not detect anything.
Any ideas? Thank you.
