If you haven't bought a new version of your antivirus software in a couple of years, now may be a good time to do so. Malware is evolving faster than ever, and the latest generation of antivirus software is better equipped to handle this rapid pace of change. If your antivirus software is a few years old, it may not be able to defend against this onslaught effectively, even if you faithfully download new virus definitions. In recent years, the technology that powers antivirus software has changed dramatically: An antivirus package you purchased a few years ago may be able to stop known viruses and other known malware, but brand-new, as-yet unknown viruses can be more dangerous, and newer products do a much better job of stopping them.
