Sorry to hear you are having problems with your virginmedia security. I have replied to your previous post regards itunes, the F1 2011 game I have not heard of any issues with this also here is guide to known conflicting programmes the only other solution I can other is to either uninstall and reinstall, if that does not work you could try a clean install of windows then reinstall see how it runs before adding the other software. If you still have the problem after that then you might want to try another anti virus product.
