If you think AVG is incorrectly flagging a file during download, try downloading other files off the same site, as well as other websites, to rule out the specific file being infected.

If there is no "Program Files (x86) " folder, open the Program Files folder.
Delete all the folders with the "AVG" prefix, except the highest-numbered version.
