Hey folks

First of all, thanks for your help a while back when I had some problems with my webcam. My latest problem is when I'm using Firefox everytime I go to a new site I my compy opens up a new window advertising something like online dating, spyware scans or just general adverts. It's really pissing me off, but I've run several Adware and Spyware scans using customised options, but still I am still interrupted by needless windows trying to sell me something. I don't think their pop ups as I have a blocker enabled, unless that's a bag of ****e itself.

I have installed and scanned my system using Ad-Aware SE, Spybot Search and Destroy and also CW Shredder as the Microsoft Spyware cleaner has suggested but still nothing.

Any suggestions are welcome, guys.

Thanks.
