Just because you have an anti virus software does not mean that you do not have any vruses. There could be a virus that slips through the gap as no anti virus is 100%. You can get really good ones or really ~love~ ones but none of them can stop all the viruses. Also you are running a release candidate version of a windows operating systems, its like saying I am running the beta version of a game and saying it has got flaws in it. There is something wrong with it and if it is not important just fomrat your computer.
