Viruses are brought into a firms network via various ways:

• E-Mail
• WEB
• media

Therefore the only way into your company network should be your captive mail server. Besides this there is often a web mail access as well which is done via HTTP and thus circumvents central e-mail scanners.
The easiest protection here is a local virus scanner like, i.e.  F-PROT. It has the ability to successfully fend off a big part of the attacks on your PC. F-PROT belongs to the most cost effective and neverthe less efficient virus scanners ans also checks archives.

For networks we additionally recommend a central E-Mail-Scanner, like the KR Business Edition Virus Protect - eine compact, fast and high-available solution.

The sensitisation of your co-workers allso belongs to virus protection. Thus web mail should be generally forbidden and only those employees who really need it should have an internet access.
