I have followed the instructions and downloaded the myriad scanning programs and applied all fixes and deletions suggested. When I open IE, the trusted files still show the dog sites as trusted until I remove them. According to AVG 7.5, I don't have a virus, etc. It did show a threat on Oct 13th and removed it, but since then it shows everything is fine. I did have McAfee site advisor (free version) and it seemed to go bonkers last week...began turning on multiple copies of itself according to the task manager. I also had problems with Adobe Flash Player and uninstalled then reinstalled it. Everything is running fine now except for the dog sites continuing to show up in my Trusted Sites. I use my computer for work and home uses, including bill paying. How I discovered that I had this virus was when my husband was unable to download songs from Amazon.com's new music site, and I was going to add it to my trusted sites. That's when I found the dog sites listed. Thanks for any help!
