Need Help with Fake Security Alerts

[Barrackade]

Please read whole post and thanks for help in advance.

I know this forum is not for Hijack This.log, and I apologize if my problem falls under that category as I am frankly confused as to what my problem is caused by.

OK so, I was on the web when I received an alert from Windows Security ( I run Windows XP service pack 3, the problem started while I was running service pack 2 though I'm not sure if that makes a difference). The alert informed me of a trojan and provided a link to download PC- Antispy, which I did download but didn't pay for luckily. I later looked up PC-Antispy on Google to find out ( from this forum in particular) that it was rogue software, after which I looked up looked up legitimate malware removal programs and downloaded them.

Anyways, I am running Malwarebytes anti-malware (registered), Spy Hunter 3(registered), Rogue Remover Pro (30 day trial) and AVG Free 2008, all of which tell me that I have no malware or virus detected on my computer, however I keep getting the fake security alerts from windows which is my problem.

SO pretty much I am wondering what is causing these fake alerts and how do I go about removing it?

Thanks again in advance for helping out.
