I seem to have been infected by a trojan hourse and it is preventing me from logging onto Btopenworld,e-bay etc. Every time I try I get redirected back to the logon page. I am running XP Pro and have scanned with A squared, adaware, spybot search and destroy, Symantech and avast. Nothing is being picked up. Any ideas? By the way I was using Bt's norton firewall. Please help.
