bugRaz-Lee’s iSecurity Anti-Virus product is based upon ClamAV, an open source toolkit. We often enconter questions from customers and distributors alike about its qualities, and about how it compares with commercial Anti-Virus solutions.

 So first – some basic info:

ClamAV is an open source (GPL) anti-virus toolkit for UNIX, designed especially for e-mail scanning on mail gateways. It provides a number of utilities including a flexible and scalable multi-threaded daemon, a command line scanner and advanced tools for automatic database updates. The core of the package is an anti-virus engine available as a shared library. For more information click here.  

 ClamAV has won the following awards:

  • InfoWorld best of open source in security, September 10th, 2007
  • 2006 Community Choice Awards, April 5th, 2006
  • Linux Format Magazine chose ClamAV as the best AV, January 16th, 2006

And most important –  ClamAV is held in high esteem by its users. Some examples of this can be viewed in forum, where users expressed their appreciation for ClamAV:

“In our particular environment (a government server farm), we were asked  to deploy the Mcafee virus scanning tools for Linux. After several months of  frustration, we concluded given our particular configuration (A very large Storage Area Network) that McAfee would never meet our needs.

We tested and deployed ClamAV across 63 machines with over 24 terabytes  of  network storage and have found that it fits our needs extremely well. We  don’t do “on the fly” scanning, but do scanning on a cycling basis per   machine, to avoid overtaxing our network”.
