With free Antivirus such as Free Avg at http://www.grisoft.com there is no excuse to do without.
Your problems will continue unabated and please excuse me as I write you are wasting a lot of people's time including your own by not having an antivirus.
There was a time when one could "practice safe hex", but with some thousands of bad people writing virus/worm/parasite/hijacks/malware/adware/more, there is no assurance you can run a PC with Windows and not have an issue without an antivirus.
That said, I now know why you have so many posts here.
