Firstly: Yes--I'm aware that there's not a single "best" AV out there. And I know that no AV will protect anyone 100% of the time.
Anyway, I am deciding on an AV for 64-bit Windows 7. Being young and addicted to the web, I'll admit I'm not the safest internet surfer/user, but at the same time I am not terribly gullible, so I won't go around clicking something that will likely harm my computer. I game from time to time, so I'd prefer something that's light on the system and don't that's not a huge resource hog (I hear Kaspersky is pretty heavy). However, I don't necessarily want to give up better security for size/weight of the AV.
Also, price isn't my primary concern (I'm willing to pay), although it'd be nice to opt for something cheaper.
Given that^^, here's my impression now on the AVs that I am considering (correct me if you feel any of my views are inaccurate). Yes, I've done some prior research (quite a bit, actually), and I've narrowed my list down to a few.
1) NOD32-- Pros: lightweight, small footprint (not sure exactly what this entails) / Cons: maybe not as in-depth and thorough as other AVs
2) Kaspersky-- Pros: extremely thorough, in-depth, huge company, great reputation for many years / Cons: supposedly HUGE resource hog and might slow down computer
3) Avira (either FREE OR PAID; IS PAID WORTH IT?)-- Pros: well, so many people talk about how great it is. i've even heard from hackers that they have trouble (albeit minor) with avira. cons: well, it tends to not make a lot of the mainstream consumer review lists, although this doesn't seem to be much of an issue.
4) MSE-- Pros: free yet supposedly matches the potency of the paid AVs. has great reputation CONS: people seem to complain a lot about MSE not detecting stuff.
Any feedback will be appreciated. Thanks
Oh--and I also hear a LOT of good stuff about f-secure. seems a little pricier/resource-heavy, though
