ady4um,
Thanks for your reply! That is good advice and I will do that if I have any other problem with my system. Since everything except the “About avast!” display window works fine, I would guess that the version 6 installs aborted before they changed anything important. I don’t care enough about the “About avast!” menu to reinstall the program if that is the only problem.
My purpose in reporting the registration reminder problem was to let other users (and Avast) know about the problem and that there is an easy work-around. I wasn’t really expecting to get a solution for the “About avast!” display, and I probably should have made that more clear in the original post.
(As for bobo, I wonder if… maybe he should be paying attention to the teacher instead of playing on the computer?
