New Christmas computer, part 2: anti-virus

You are savoring your new PC and visiting your usual haunts: Facebook, Netflix, Hulu, and more.

But if this new PC does not have anti-virus, a firewall, and other precautions, the glitter will soon be gone, and you’ll soon wonder why the problems you’re having in 2013 are related to that new PC.

New machines are a good time to develop new habits. Sure, there’s a little trouble now, but you’ll save hours of grief later.  Think of this as the moments required to fasten the seat belt in your car and perhaps a bit of discomfort – but compare that to the pain and expense of injuries incurred in even a minor crash if you weren’t wearing it. Minor decisions now can have major consequences later.

Habit #2: Install and configure anti-virus

While many new computers come with anti-virus software, often it’s a limited “trial” version from one of the popular brands such as Symantec, McAfee, or Trend Micro. If you don’t mind shelling out $40 or more for a year (or more) of anti-virus protection, go ahead and do so now before you forget. Granted, most of these trial versions are aggressively “in your face” about converting your trial version into a full purchased version.  Caution: if you get into the habit of dismissing the “your trial version is about to run out!” messages, you run the risk of turning a blind eye when your trial anti-virus is no longer protecting you.  Better do it now!

If your computer did not come with anti-virus software, I suggest you make that the first order of business. There are many reputable brands of anti-virus available today, available online or from computer and electronics stores. For basic virus (and Trojan, worms, key loggers, etc.), all of the main brands of anti-virus are very similar.

My personal preference for anti-virus programs (in order) are:

1. Kaspersky
2. Sophos
3. AVG
4. Norton
5. McAfee
6. Panda
7. Trend Micro

Note: if selecting, installing, and configuring anti-virus seems to be beyond your ability, consult with the store where you purchased your computer, or contact a trusted advisor who is knowledgable on the topic.

Key configuration points when using anti-virus:

• “Real time” scanning – the anti-virus program examines activity on your computer continuously and blocks any malware that attempts to install itself.
• Signature updates – the anti-virus program should check at least once each day for new updates, to block the latest viruses from infecting your computer.
• Periodic whole disk scans – it is a good idea to scan your hard drive at least once a week. If you keep your computer on all the time, schedule the scan to take place when you are not using the computer, as a scan can slow down your computer.
• Safe Internet usage – many anti-virus programs contain a feature that will try to warn you or steer you away from sites that are known to be harmful.

Many anti-virus programs also come with a firewall and other tools. Some of these may be useful as well – consult your computer retailer or a trusted advisor to see what’s right for you.
