Ive installed avast on my pc and am now having major problems with it. It seems to stop me using internet explorer and everyday I have restore it from an earlier point. I cant seem to uninstal avast either, though Ive tried countless times. I'm a novice when it comes to anything like this. Would someone be kind enough to lay out some steps for me to get it back to normal. Any help would be much appreciated, thanks. I'm on vista by the way, if that has anything to do with it.
