Hello,
None of those things worked.
I tried the entire list and it still does the same thing. My current anit-virus situation is that I do not have one. I had a trial to Trend Micro PC-Cillin, but it expired the other day. I went on the Internet to download some sort of antivirus program for now. Sort of ironic. Anyway, I went to the Panda Software website and did their system scan and it said that I did not have a virus or anything harmful.
