I have AVG free. Every single time I restart the computer AVG pops up to say it has found a trojan (various ones). Every time I remove it successfully. If I then restart another one is apparently found. A full scan shows up nothing. What is going on?

Karen, For your info, just in case that you are unaware, you can post the screenshot here in your topic. Click on 'Answer' & then click on the 'Image' [mountain symbol] & follow the instructions.
