Okay, my computer was infected with the Security Toolbar spyware?

I have Avast antivirus, and Microsoft Defender programs on my computer, and neither can find it. I downloaded SpyOnThis, but I don't have the thirty dollars to register it, and that's the only way it will delete the suspicious files. How do I get rid of this?

*Security Toolbar can be uninstalled from Add/Remove programs, if not there, it will be found by one of the scans suggested below.

Uninstall ''SpyOnThis'' from Add/Remove programs. It is on the list considered to be RogueWare. Anything that offers a free scan, but, wants money to delete it, is not a good tool.

Use these instead, they are always free and if it's a trial, as with 'Trojan Hunter', it will delete what it finds until it's trial period is expired.

See below:

Download, Install, UPDATE and run scans with these programs and Quarantine all they find:

Trojan Hunter (free trial)

SuperAntispyware (free)

AdAware 2007 (free)

After that is done...

Perform another full scan using your Avast! A-Virus once again. No more detections? Good.

Next, you need to:

Delete all Temporary Internet Files-
