I have an XP home machine that I'm working on. It had a typical rogue antiviurs. I'm thinking it was called Antivirus 360. Either way, I manually killed the EXE that was living in the APP DATA folder. I then rebooted, downloaded ComboFix and cleaned it up. ComboFix deleted USBSTOR.SYS as it was infected. I replaced it from a know good computer, along with USBSTOR.INF and PNF. However, the system still locks solid as soon as you insert a USB Flash Drive. The flash drive worked prior to cleaning the infection.
Thanks in Advance
