Antivirus 2009

I've seen multiple other threads about this same issue. I have ran Malwarebytes and SUPERantispyware. I have also used hijackthis, spyhunter (scan only), spybot s&d, roguescanfix, adaware wont pop up. Malwarebytes removed the taskbar icon, but I am still getting the anoying pop up, that takes me to a phony antivirus site and the ALERT you have a security...blah blah. I have ran all the programs in safe mode and all the other ways I've read in blogs. Can someone please help! I'm not sure if this virus is dangerous, but I log off my wireless connection except when researching/trying to fix this. Thanks to anyone that can help me.
