I swtiched to AVG instead of Kaspersky, K7 was just too resource heavy and whenever it ran any processes it completely wrecked my bandwidth. I don't understand the link scanner in AVG at all. I googled some of the most illicit sites I could think of and AVG gave me a "green thumbs-up a-ok to visit" ranking for all of them, so I don't know what it takes to trigger a warning from that feature.
I like AVG's non-intrusiveness tho, it's a far cry from what I experienced with it back in the day. I hate software that takes over the PC (>cough< Adobe >cough<) and frankly the anti-virus industry is just rediculously over-blown. I don't need notifications that all is well, just tell me when something's wrong.
