revenue optional in some cases
I've been using sophos for years at work and it's worth the money, but they've recently branched out into a "home" edition - which is free.
It's worth trying out.
Re: revenue optional in some cases
Until recently they allowed Enterprise customers to distribute a standalone installer to its End Users for use on their home machines for free always considered this a nice touch from an AV vendour I first came across nearly 20 years ago when updates were distributed by me walking around the Office with a CD that Sophos posted to us in a monthly basis!!!
