Least disruptive anti virus while working [closed]

Solution 1:

Nod32 in my opinion has been going down hill recently but it is still fast and good. As you have (hopefully) already paid for licences, I would not bother to switch at this point.

When you have finished your conract and are looking for a new AV, I have been using Microsoft Morro http://www.microsoft.com/security%5Fessentials/ and am VERY impressed by its footprint and speed, however to my knowledge, it has no central management.

For paid, enterprise AV, I think NOD32 is still very good, I just hope they don't go down the Norton / Symantec route and start to take the money out of advertising and back in to development!

Edit - Someone else just posted a link, did not know it was openly available now.

Solution 2:

That would be ClamWin. It only scans when you tell it to, and when you use emails.
