Can someone out there help me please. I had Norton on my fairly new computer and when it ran out I mistakenly downloaded Avast BEFORE uninstalling Norton. When I did finally uninstall Norton it messed up my securty system terribly. I cannot open several Windows functions (such as System Restore, Search, etc., etc., etc.) My Google doesn't work properly, I cannot navigate around the internet, my EBay is messed up, my Windows Media Player is not functioning, and the list is endless. It is so frustrating and I have written directly to Avast for help but they are not replying, and I can get to Norton because I can't get around the internet!!!!! I am sure hoping someone can help me. I am running Windows XP on a LAN and have downloaded Avast 4.7. Thanks
