good question...difficult answer.

Perhaps you let some external advise lead your hand when purchasing the next AV package.

Things that are important when making a decision are:

• A good detection rate is paramount. The level of detection is permanently tested by third-party companies. We would strongly suggest to check the ItW certification by consulting any of the following:

- VB100% ( http://www.virusbtn.com),
- ICSALabs ( http://www.icsa.net)
- Checkmark ( http://www.check-mark.com)."

• Check the system requirements before you buy. When using Windows XP or Vista, any antivirus software should work. If you have an older or slower computer, however, a large antivirus software program can consume a huge percentage of your computing power. Check the Comparison Chart for system requirements for the software included in ConsumerSearch Best Reviewed.
• An intuitive interface makes it easier to make use of the vast amount of configuration settings for the product by guiding the user through the various settings.
• Daily updates of the virus definitions are essential. Most products provide one year of unlimited free updates. After that, you renew your subscription, buy an updated version of the same program or switch brands. Virus signatures are specific strings of binary code that can be detected by antivirus software. Most programs will automatically check for updates.
