Just over a week ago I started getting additional web pages popping up. When I visited sites I usually go to, I keep getting a second web page. The three I get are: any-purpose-loan.co.uk, ad-doubleclick.net, winantivirus.com. The first one is an advert but the other two are just blank pages. I have Zone-alarm firewall, Norton anti-virus, Spystopper and have just recently loaded Counterspy to see if that helps. I also have a router that has a built in firewall. I run Spybot and Ad-aware once a week at least. I have done nothing different that should make this problem happen. I assume there is some sort of spy-ware but cannot understand why the various software does not clear. Suggestions please.
