I also tried to do a System Restore and was told that there were no restore points saved.
For the last week I have been trying to figure out why I cannot get streaming video over the internet. I thought at first it was a wrong IE8 setting. Then I thought that either I lost Adobe Flash Player 10 or it was being blocked by AVG 9.0 Free Edition. I ran a full AVG virusscan which was negative. I ran Malwarebytes full scan which was negative. I tried to run PC Cillin Housecall but kept getting a message that the website is unavailable. I removed AVG and tried again. Same problem. I tried to re-download AVG and it tells me that the site is unavailable. I know that somehow I have a virus but I don't at this point know how to find and eradicate it.
