Mary Landesman wrote an article on About.com, which brought up some interesting points. Three different free antivirus solutions were tested: AntiVir PersonalEdition Classic, AVAST 4 Home Edition, and AVG Free Edition. Of these; AVAST! (Which I use.) fared the best, detecting 92% of zoo viruses. AntiVir came second with an 85% detection rate, and AVG was in last place with only 81% detection rate.

When it came to being fast at releasing updates against major threats though, AntiVir was tops, with Avast! in second place, and AVG once again lagging behind in last place.

Although all three solutions claim to give protection against spyware and adware, they’re all fairly lousy at doing so. Avast! was again the best; despite scoring only 33%. AVG was yet again in last place.

As with everything else, you get what you pay for; so if you need an active all-round security suite I personally recommend the paid-for Kaspersky Internet Security Complete Protection , which has in test after test proved to be one of the best security solutions on the market. Linux users and geeky types may prefer NOD32/Eset Smart Security, which is also one of the best out there – Although I personally found it to be a bit bloated when I tested it last year (2008) in November.

I remember back in the days in the 20th Century when I was running Windows 98SE I had Trend PC-Cillin installed, (Not free) which failed to detect a particularly virulent virus which subsequently infected my system and disabled all protection. I installed a different paid-for solution, (I forget the name of it.) which the virus couldn’t disable and which detected and killed the virus. That goes to show that no antivirus solution; free or paid-for, is infallible.

I’ve always scanned with Lavasoft AdAware on a weekly basis anyway. – So if anything is missed by Avast! then AdAware; probably the best anti-malware solution I’ve seen, even topping Malware Bytes, will remove it.

What antivirus or security suite are you using? How would you rate it? Please comment.

Added 16th December 2009: Since I wrote this article a new free antivirus solution from Microsoft; namely Microsoft Security Essentials, has been released. In the opinion of myself and other testers; all other free antivirus solutions suck in comparison, and I strongly recommend that, if you’re not prepared to pay for an antivirus/malware solution, you download and install Microsoft Security Essentials
