I've got the best virus protection ever..... ...its called a Mac.
I used to use their firewall up until the latest incarnation and had no end of issues and a nightmare to totally remove. I recommend Avast (for antivirus) to friends looking to get away from paid options - no problems with it in 5 years or so
Stuck this on a win 7 machine and it was ****. Free is free but even Avast, MSE and others offer working freebies
1500 infections?!? That's a lot of porn ... ehm, I mean 'social media'. To be honest I don't think there is anything massively wrong with zone alarm - while I was using it happily over the years I read other people complaining of experiences similar to my recent one - I suspect there are many people for whom it is working fine right now, it just won't play nice with my current setups. It is a big exe file though, and an unacceptable load on older pc's.
To be honest I've been fine with MSE and Windows firewall. However the PC I'm cleaning had over 1500 infections so basic stuff no good for him. Seriously considering putting Ubuntu on it as he doesn't seem to learn. Kids eh?
