Deb, The solution appears to be updating virus definitions. Have a look @ this link (https://support.avg.com/answers?id=906b0000000DK4mAAG).

Hi:
2 days ago my system scan detected 60 of the above Trojan Horses and deleted 30 but I was unable to delete the rest. I have Win XP with Service Pack 3. I do have an older version of Free AVG. I have tried updating my free AVG but I cannot launch Chrome browser now. Can you tell me how to get rid of these 30 infections please. I did a system restore but they are still showing in my AVG. I am using work email as do not want to use home computer until I can fix this problem. Thank you.
