Online Armour is a great software for security if you’re intrested in a premium purchase and subscription expense.
The subject is quite contentious, but my recommendation for no purchase / subscription expense product is Comodo Internet Security FREE. They do have a licensed version, but the extra bell and whistle IMHO can be done w/out. Unless the user absolutely needs someoby to hold their hand (24/7 phone support may have its merits)
It has all the protection of FWBuilder, IPTables and Squid for ‘Nix systems. Its AV is very good. Quite frankly, if anything gets through a properly configured Comodo firewall & HIPS (host intrusion protection) it is because the user allowed that to happen and they deserve their malware infection. Just like the law, ignorance is no excuse.
That nowtisthstanding, Comdodo does require some user expertice with regards to configuration for ultimate protection. The neophyte user settings are pretty good though. Configuring Comodo for maximum protection will force the user to become intimately familiar with normal functionality of their system. THAT is the first defense against becoming hijacked and infested.
No sane user would rely on a ‘blackbox’ for their security and anti-malware software though; it is naivete at its most foolish epitome.
I would strongly recommend against using Zone Alarm for a firewall.
