Like most of the products tested here, NAV is certified by the NCSA to protect against known viruses, and it performed as billed. The program performed equally well on macro viruses. By default, NAV scans the largest selection of file types among the products tested, but its scanner was one of the slowest on our tests. Faster and more selective scanning would greatly enhance this product. Wizards guide you through scanning and disinfecting chores, and Symantec's LiveUpdate feature makes it simple to upgrade the virus-definition files.
Updates are free for the life of the product.
Only PC-cillin II had the same performance hit. A couple of other programs warrant mention. A newcomer to the U.S. market, ViruSafe 95 also scored perfectly on the WildList test. But like NAV, ViruSafe could use a faster scanner. In addition, we quickly grew weary of the program's animated sequences.
