Now I know why I don't use Sophos. They don't know what they are talking about. My anti-virus had 2652 new virus signatures added in May, not a meager 959. They have a free online scan, and they most frequently detected Netsky.P last month, it just depends on who you are listening to. Now, which would you rather have, Sophos and be protected against 959 new viruses last month, or mine with over 2000 (I will keep mine). I don't use Norton, I don't use McAfee, in fact, you've probably never even heard of mine. But I bet you will never find a better one.
