Sophos

This is going to sound like a sales pitch, but I assure you I am not being paid by Sophos to say this.

I've been deploying Sophos Anti-virus at work in stages over the last month or so, and I am continually amazed at how many of the JavaScript Trojan droppers and Fake Antivirus programs it is finding in people's temp and temporary internet files, or buried in system restore points that the previous antivirus just plain missed.

I'm not talking about bleeding edge definitions for variants that just came out the day before the switch either. I'm talking about stuff that's been sitting in temp for months in some cases.

If you are curious how it'd do in your environment, download the free removal tool and run a one time scan of your system. or sign up for a trial of the full thing. It really does find stuff that the other guys miss. http://www.sophos.com/en-us/products/free-tools/virus-removal-tool/download.aspx

Sophos doesn't have a home user product like most of the other antivirus companies, but even for small businesses they have packages that are fairly affordable, especially if you bundle several products. With our government pricing we managed to get a replacement for our antivirus including e-mail servers, plus a spam appliance as a VM and mobile device management, endpoint encryption, and a few other things for about what we were paying for maintenance on the anti-virus parts with another company.
