Recommendations for Anti Virus software?

I've used several, and for some years. I currently use Kaspersky, having switched from McAfee. I did ask some of our PC geeks at work about what they recommended, and was mainly met with "Whatever you can get free, or the cheapest" Not much help, then!

I was put off (old) Norton, as I kept on hearing about it being resource hungry - the "new" Norton isn't, and now has positive reviews. One of my colleagues uses it and says it just scans very quietly in the background (on an old laptop). I would certainly consider Norton now.

McAfee: Resource hungry and seems to throw up regular compatiblity issues with Windows and Adobe. I struggled for about a year with a Vista incompatibility problem before (I think) M**rosoft forced McAfee to rectify the problem that they had previously ignored. I can't recommend McAfee due to this and the fact that it is bundled with loads of off the shelf PCs. People are invariably lazy and just use what their PC comes with, usually paying the subscription when required.

Kaspersky: It's good and does the job very well (picked up 2 trojans on an eBay page before the page fully loaded). Kaspersky is also a refreshing change in the AV world as it's "labs" are based in Moscow! I'd say with the amount of malware that pours forth from Eastern Europe, they are in a pretty good position to be at the front line, rather than waiting for something nasty to hit American servers and sort it out from there. Kaspersky updates very regularly, and these many but small updates slow things right down. They are a pain, but I can live with about 3mins of slowness every hour or so.

Personally, I'd go with the newest Norton, or Kaspersky.

To be honest, I'd not bother with "my new antivirus found a virus that my old one missed" - All AV programs vary in their effectiveness, and if you beleive the conspiracies, then each AV company employs their own "virus writer" who writes something quite product specific, with the aim of devaluing a competitors AV product.
