For the past month I have been plagued by pop adware that will randomly appear, usually during startup. Scans by SAS indicate I am infected by:
Rogue.Agent/Gen-Nullo[DLL]
C:\WINDOWS\SYSTEM32\12481871641.DLL
Upon removal, the computer appears free of problems, but problems will often recommence some hours later, or during reboot.
Subsequent scans reveal the same file, however with a different number. Clearly the file is replicating itself.
Has anyone else experienced this, and how do I permanently remove the infection?
