antivirus soft- posing as windows security program

hello, i found bleepingcomputer searching for a solution to this infection "antivirus soft" a very nasty program that has taken over my computer. it popped up suddenly and kept popping up window after window asking me to scan & saying i had major infections. after finding this site i followed all instructions to remove from this page http://www.bleepingcomputer.com/virus-remo...-antivirus-soft. i use firefox instead of explorer so i was able to download & use rkill & then downloaded and ran malwarebytes anti malware all as instructed. and vioala! it was gone.. i was happy. but after restart BOOM it was back. so i started over, followed all instructions with same results, any restart and it's back. i looked in startup under msconfig, looked in add-remove programs, looked in hkeys in regedit ( i'm no pro, got lost in there) can't find anything for antivirus soft. also looked in task manager and found nothing there.

if anyone can please help me from here it would be greatly appreciated. i run win xp pro p4 300 1gig ram & have adaware free version for antivirus (it missed it) thank you in advance for any help

Should work for you. You could also boot into safemode with networking. Install malwarebytes, update and run full scan.
