I usually use AVG for my AV requirments, but since i have bought a new laptop with vista on it, AVG is not running too well and norton is a resource hog... can you recommend a good AV for vista (it should be totally compatable and reliable)
Also kindly tell me why you recommend it... have you used it? past experiences.. anything.
Note: It does not have to be free... commercial softwares are fine. (If you work for the company you are promoting kindly also mention that)
