"Windows Security has found critical process activity on your system and will perform fast scan of system files"
This has not happened since the incident and it was the only time it's happened in two weeks.
I'm on a Windows 7 64 bit system so ensure that any programs you tell me to run are compatible. Last time chewy had instructed me to run TFC, which isn't really compatible with w7, it didn't really hurt anything, but just saying!
I've run MBAM, Spybot, Super Anti-Spyware, all of which found nothing.
I would post this in the other subsection but honestly I'm afraid to run anything that makes any immediate changes and wasn't sure if tools such as DDS, Hijackthis, and GMER do make immediate changes or not.
Edit: Oh and I was wondering if I should just run the IE fix tool my MS before I try anything else to attempt to get rid of this, as no other browsers are affected and I've noticed nothing else strange including any process or system hitches. When the tab came up I properly exited out via Alt-F4, I did not click the pop-up at all.
edit2: I had figured out how to work HJT and didn't notice anything suspicious myself checking through all entries. Perhaps it was a one-time incident, my parents were on the computer when it happened and they called me over to check it out. I know HJT is a bit outdated though, so help!
