Hello, I run AVG Antivirus. My homepage got hijacked and I simultaneously acquired the alleged XP Antivirus softwarer which I can't remove. When I try to go online using Internet Explore (my default browser) my computer shuts down and reboots. Fortunately, I had Firefox on the computer also and I am using that right now. I keep getting notices from this XP Antivirus that I have 199 infections and I have to download the program NOW. I haven't clicked on anything. Here is my Hijack This log. Thank you very much.
