So far, most of my searching didn't turn up anything for my case, but it seems this is caused by Vundo...a pretty bad Trojan with a lot of variants...however, there are a few programs to try: webroots spyware sweeper (has found vundo but is still scanning so...?), http://www.atribune.org/downloads/VundoFix.exe for VundoFix.exe which supposedly finds a lot of variants, and http://securityresponse.symantec.com/avcenter/FixVundo.exe for FixVundo from symantec...which didn't work for me, although it claimed to.
It seems a key feature of this malware is to cause a popup every few clicks, especially to WinFixer or an IP address with an 'errors found click to scan' type of page being displayed.
*note* spysweeper just finished scanning...it found a few things I knew about (keyloggers i was trying out), a couple I didn't, and it identified pmnkl.dll as an adware file.
