Antivirus Software

In part one of Protecting Your Digital World, I wrote about the need for an antivirus program to constantly check your systems for viruses, bots and other malware trying to control your computer. Now, let’s look at some of the applications that will help protect your system. Check each product carefully to see how it is licensed before spending your money. Some license their product by the computer while others require a license for each user. Many require annual subscriptions for virus definition updates. Be sure you understand all the costs before making your purchase.

  • Windows Security Essentials is a free download for Windows 7, Vista and XP users. Once installed, it automatically checks for updates daily. It’s notification system will tell you if a trojan or spyware app is trying to install itself on your system and you can perform both on-demand and scheduled scans of all or parts of your file system.
