Hi Everybody, the Norton program was recommended for my computer by HP. I've never questioned it. I have noticed that they are intrusive... I fixed my Spy Sweeper after I installed a new driver and chip set, that's been ok. I installed Messenger 8.5, no problem with Norton. I started having problems with Norton after I activated my WI-FI. Spy Sweeper picks up the Cookies after I use it- no problem. Norton sticks during the middle of a full scan and won't turn off when I ask it to. Suddenly it cuts and can't find anything wrong. I can't turn off my computer without cutting power. Spy Sweeper will cut in during Norton's scan and say that two programs are trying to re-write my host's file and that I should block if I don't know what they are doing. Anybody have this problem?? Sincerely, Celestra
