After running combo fix on Thursday, the pop ups ceased. The pc wasn't turned on at all after Thursday as I was off Friday and the weekend.
The pop ups started almost immediately on turning the pc on this morning (Monday 9am est)
Ran Essexboy's fix and rebooted, the pop ups are still coming. Granted not as frequently, but still there. Most concerning webgetclick.com
I can't see AVG showing up anywhere, but trend still appears in the OTL logs as a firefox extension, although the only extension I see in Firefox when I open it is fireftp.
Yes I did run the uninstall from the website you posted.
Attached is the lates OTL scan.
I really hate computers!
