As many of you know, I have just recently switched from using AVG over to using avast!. The new AVG 2011 made my system sluggish and was bloated so I reluctantly made the switch. I have also advised many times never to rely on any one anti-virus program as your sole line of defense. I personally will use Malwarebytes, Spyware Terminator, or one of the fine online scanners listed below, to periodically scan my system for critters.
What brought this all to mind was a computer I worked on yesterday. It belongs to a relative and they were experiencing reboot problems. The computer was running an older copy of AVG 8.5 that I had installed when they bought the computer. Yesterday I ran Malwarebytes which found 42 viral infection which I placed into the vault. Uninstalled AVG 8.5 and installed avast! version 5, it also found two more bugs.
In addition to the two programs I have mentioned above, I also use online scanners about once a month. I rotate the scanners, never leaving it to any one system to find and eradicate any bugs that my system may pick up. The online scanners I recommend are:
F-Secure Online Scanner
There are others available, but I use these four, rotating them through the months. I have not had an infection on any computer I have every used for well over 10 years. The reason is simple. I have a secret weapon and it is the best anti-virus program in the world. It is called Common Sense 2011. 🙂
By using my brain I stay away from areas of the Internet that pose a hazard. I never lurk where danger resides and confine myself to reputable Web sites only. I keep my eyes open for anything suspicious, use two separate scanners to warn about rogue sites, and basically confine my searching to where the good guys are. That, my friends, is why it is called Common Sense. The 2011 model will start on January 1st, 2011. It has worked flawlessly in the past and I have no doubt it will do the same in the future.
