I am running Microsoft Windows XP Media Center Edition Version 2002 Service Pack 2. I am also running McAfee Security Center. I was running Internet Explorer 7 then recently switched to IE8 then switched to Mozilla Firefox. I then started getting "artemis!..." and "vundo..." quarantine messages intermittently and after scans by McAfee. I thought perhaps that it was related to the web browser change and so I switched back to IE 7, but I am still getting these messages. I have run McAfee scan numerous times and it quarantines both "artemis!..." and "vundo..." however it continues to show up even after it is removed.
Also, recently, IE7 would start numerous new tabs on its own. The new tabs are empty pages but have "url.urtbk..." on the address bar. IE7 would also close/exit without warning and pop-ups would appear out of nowhere even though the pop-up blocker is enabled.
Reading some threads on the internet, I tried to download malwarebytes anti-malware, however, an error message at the end of the installation process comes up and I am unable to start the program.
I aplogize that my knowledge on this material is limited but I would really appreciate any help/advice/suggestions on how I could clean this up and also on how I could prevent this from happening again.
