Hi, I've been running Vista 64-bit for over a year now. When I first installed it, I got whatever free AV was supposed to work with it (there was only one at the time), but it wouldn't install, saying that it wasn't supported. So, from then until now, I've had NO antivirus installed. I installed AVG 8 on a customers computer earlier this week (the only reason I don't use AntiVir is the popup message), and liked it. I installed it on my system and it installed just fine. I scanned, and all it found was what I expected; as a tech, I have lots of techy tools that most AVs don't like seeing on the computers of mere mortals. :) I have a router (which acts as a hardware firewall), and I also have a Smoothwall box, which also does some blocking. I also have the Vista firewall running. Vista, of course, comes with IE 7, which has more protection built in than 6; I have the phishing filter and popup blocker turned on. For some reason, I haven't used Firefox in a while. I keep Windows and applications (such as Java) reasonably well updated. HEAR THIS! I don't normally go to "dark alley" sites, look at spam, and so forth. If I did, or if I had other people using my computer that I thought were not very discriminating, I'd have run-not-walked to an AV that would install properly on Vista 64. The only reason I didn't have infections was because I have a NAT router and because I avoid things like spam, porn, warez, and sites with excessive amounts of advertising. This is not something that I'd recommend for the average user. Effective antivirus programs: The April edition of Virus Bulletin announced that 5 programs scored 100%: Avira Antivir Personal ESET NOD32 Fortinet FortiClient Frisk FPROT Antivirus Symantec Norton Antivirus Of those, only AntiVir is free. Runners-up, scoring 98-99%: McAfee Antivirus Enterprise Microsoft's Forefront Security Client and Windows Live OneCare Webroot Spysweeper Bitdefender Antivirus 2008 CA eTrust Antivirus and CA Internet Security Check Point ZoneAlarm Kaspersky Antivirus MWTI eScan Internet Security Redstone Redprotect Sophos Anti-virus Bullguard Well, perhaps I should take another look at Avira AntiVir. ************************* Firewalls: A company named Matousec Labs tests firewalls, considering a number of factors. You can see their results here: http://www.matousec.com/projects/firewall-challenge/ For those who want a short summary, 2 programs get a 100% rating, and both are free. Comodo, of which I've heard much good, is one of the two; I installed it on a customer's computer the other day and liked it. It has modes for training (on a clean computer) and for installing. Zone Alarm scores 74%. Norton, Sunbelt, Avira, AVG, PC Tools, McAfee, Windows Live OneCare, and BitDefender firewalls scored 18% or less. How much less? Try 5% for Windows Live OneCare. -- Scott. -- -------list-services-below----------- Regards, John Durham (list moderator) <http://modecideas.com/contact.html?sig> Freelists login at //www.freelists.org/cgi-bin/lsg2.cgi List archives at //www.freelists.org/archives/pchelpers PC-HELPERS list subscribe/unsub at http://modecideas.com/discuss.htm?sig Latest news live feeds at http://modecideas.com/indexhomenews.htm?sig Good advice is like good paint- it only works if applied.
