a good program to run is 'hijack this'. this program looks at all registry, system, etc changes (ie. homepage changed to pelican
) and asks which ones u want to 'fix'. this program should show what is causing the problems. there used to be a forum that would help people if you posted up your .txt log file. they would say which ones to fix and which to leave alone. the really great thing about it is that its only like 100k.
