system
5
I also have this happening.
A few days ago, before i shut down my computer for the night, i got a reoccurring problem where a small window would keep popping up saying Error in the title bar and then ‘runtime error 5 in [i believe a hexidecimal number]’. Of course, there was a number where I typed that. It would keep popping up even after hitting ok. I checked in task manager to see what program or messed up task could be causing this. I noticed that every few seconds a process, msnnuu.com would quickly pop up and then disappear at which time IEXPLORE.EXE would run. Ending process tree did not help, nor did restarts, in addition to slow/wierd shut downs and restarts. I suspected a virus, so I downloaded avast, and it did detect one, the same one you mentioned, smae location. I initially tried to repair, but it didnt work, and then tried to delete all prior to boot after restart. Many files were deleted but that same one would keep returning. I tried a system restore but it did not complete.
Btw, a major problem here too is that after disconnecting from the internet to prevent information gathering by the virus, all the IEXPLORE’s keep slowing down the system, each instance using around 9000k of resources.
