Hmmm, I may have screwed up here! I did a system restore this morning (had some of these problems at that time as well) Anyway I had installed, uninstalle Avast so many times that I couldn't use Avast anymore, my browsers were timing out, couldn't use Thunderbird, couldn't connect to the net hence system restore. So I am running repair now or should I restore back to this morning and then do what you suggest. I'm just about nuts now, lol!
Cheers,
Janice
