Undo recent changes done by avg tuneup

I recently tune-up my computer with avg and I removed  something that shows unread emails darker than the others and it makes it hard to distinguish between them. I think it might have had something to do with shading. It was a list of things running that are slowing my computer down. Is there a way to find out what changes were made to delete programs so I can chose what to startup again. Thanks, Mike
