I have been fighting the Fake.PAV virus for a week. I think I am fully updated on my Windows XP Pro, SP3 machine. When my infection started I was using a fully up to date Norton Symantec Antivirus tool. (I uninstalled it when I noticed it interfering with Microsoft Security Essentials after I installed it.) I've used Malwarebytes, Spy-Bot, MSE, and the OneCare Live Scan. The virus has modified my version of internet explorer 8 so that some of the features are no longer available. (like tabs) It also has stopped Windows Update from functioning. I can manually update the Antivirus definitions and that seems to help. I have noticed I get random Popups whenever I'm on the internet and the Pop Up Blocker for Explorer 8 appears to be disabled. Help?1 person needs an answerI do too

Hi DapperDoug, I'd suggest you run a full virus scan in safe mode with networking and then check. Note: Please use the Ethernet cable/network cable in case your computer does not support safe mode with networking in a wireless state. If the virus is not flushed out, please post your issue in Microsoft Security Essentials Forums for best support.
