What's right for me may be a disaster for you. I wouldn't have too many "active" programs standing on guard at once---by that, I mean programs that are running more or less as firewalls---perhaps no more than 2 "hijack" ones plus your regular firewall. For what it's worth, I have Spyware Guard, TrojanHunter, and Zone Alarm actively running when I'm connected---plus of course AVG antivirus. This seems to keep the system reasonably clean, though being a bit of a freeware junkie, a lot of spyware does need cleaning out every couple of weeks. For that, I use Spybot, AdAware, and occasionally one called "A-Squared 2" which looks good and seems to catch most of the nasties---and is very configurable. Shame it's not better known. And remember, each is only as good as its most recent updates. There's no harm in having plenty of scanning progs---the more the better. These are the passive progs you only run when you want them to scan the system--perhaps once a week, depending on your internet habits. Now, turning to Annie Bradley's problem, I'm wondering if you have one of those viruses that disables Nortons. With AOL Messaging, especially if you have broadband, I'd be using a lot more protection than that. Without a good firewall, you are inviting disaster. I've never used AOL (and never likely to) but from what I read, it is as much a prime target for security hackers as is Windows Messenger. Do an online virus check, and use the various spyware progs which Sven has mentioned in his always excellent advice. Yes, every one of them. Free online checks, all highly recommended: http://www.housecall.nl/ (in German, but just click the "scan" link) http://us.mcafee.com/default.asp http://www.pandasoftware.com/activescan/ http://housecall.trendmicro.com/housecall/start_corp.asp Also go to the Shields-Up website, do the security scan for your computer. You may find it rather an eye-opener, well worth a visit. Download the 3 free little security patches you'll find there. These will help a lot in securing your computer. https://grc.com/x/ne.dll?bh0bkyd2 Don Penlington From the Beach at Surfers Paradise in sunny Queensland.
