To protect yourself, rely on an antivirus package that zaps macro viruses along with the more traditional DOS and Windows boot-sector variety. When it comes to antivirus protection, you want the utility that finds the most viruses before they find you. And that program should eradicate the intruder and repair any damage it has left behind. Norton AntiVirus 4.0 brings strong virus detection with patented heuristic technology for sniffing out previously unidentified viruses. This may be more marketing smoke than antiviral fire, but it can't hurt to be prepared.
Viruses travel quickly.
You have to be quicker. No matter which antivirus package you use, you should log on to the manufacturer's update site once a week to download the latest detection files. Plus it has an extremely intuitive interface. If you aren't intimidated by a clunky interface and want the finest antivirus technology along with detection files that are updated hourly, check out F-Prot Professional. It also excels at scanning inside ZIP files of every imaginable type.
