Although F-Secure may not be the first name in anti-virus that springs to mind, its products are among the heaviest hitters in the industry. Unlike some products which depend purely on their signature lists to be updated, F-Secure also comprises multiple scanning engines and heuristic detection techniques that make it one of the first products to detect new viruses. The company has now brought its expertise to bear in email security with F-Secure Anti-Virus for Internet Mail.
The product is available for Windows (NT and 2000). A Unix version would be nice, although there is a version for Unix which sits at the firewall level. Installation presented no headaches. However because of the way the product works, disk and memory requirements are quite high. It is also better to share the scanning across more than one scanner server to keep bandwidth usage lower.
