Windows Server AntiVirus [closed]

I am switching from Symantec. I narrowed my selection to the following

1. AVG
2. Trend Micro
3. Sophos

I am leaning towards AVG for 2 reasons

1. Ease of use
2. Cost

Any input?

Solution 1:

While hearing from other admins is always a bonus, I also look at sites like av-test.org and AV-comparatives to see what their tests have for the state of antivirus solutions. I hate using AV's anyway...can be resource hogs and they're kind of a band-aid solution. But that's just my opinion.

Solution 2:

Despite having used it for years, AVG is becoming such a resource hog I no longer recommend it to anyone. Sophos isn't bad but also far from perfect. Either product has a better track record than Symantec (what doesn't?). Never used Trend Micro, so can't comment on it.

ClamWin has already been suggested but it's my opinion that if you don't have on-access scanning you may as well not bother at all. Detecting an infection through a scheduled scan is pointless - the damage has been done. It's a bit like doing up a seat belt after having a crash. Some may argue that the purpose is to detect infected files, even if there is no actual virus activity. The problem with that logic is you won't know if that file has been spread yet, or how far. On the other hand, ClamWin is fantastic for things like email scanning.
