Good Antivirus + Firewall

I would never put anything Norton on my computer.

Nod32 is arguably the best antivirus. AVG is likely not as good, but it's free and at least pretty good.

Firewalls, I'd put Comodo and whatever "Tiny Personal Firewall" is named nowadays on your short list. I think Kerio might have sold it now and it's named something else. Otherwise, just put Comodo on your short list. I think the current version's ease of use has taken a step backwards, seems a bit counter-intuitive when trying to do certain things with it, but overall it does a good job and the price is right.

 

Foolproof Idiotproof Antivirus

I'm about to help someone with an internet cafe and i'd like an antivirus that can withstand the most clueless and the most purposeful idiot. Any suggestions?

 

Avira Antivirus

Windows cannot send updates due to Avira Antivirus (not Aviva) - they suggest uninstalling Avira but it is not listed and I am not aware that I ever downloaded it. Presume its some sort of malware - any suggestions please if anyone has had the same problem
- thank you
