Zen Internet implements free virus checking for Broadband and cPanel Linux Web hosting customers with e-mail hosted on our e-mail platform (mailhost.zen.co.uk), automatically scanning mail at our border mail servers to reject viral payloads before they can enter our network.
The system in use is ClamAV, and the virus definition database can be updated up to 24 times per day, and long before anything can reach your mailbox, Zen's mail scanners check messages for over 10,000 viruses, worms and trojans. All the usual suspects like Klez, Swen, the various Mimail.X's, Sobig.X, and many variants, are catered for, and the next big threat will always be included as soon as it has been detected.
Below you can see a graph illustrating the top 10 e-mail viruses detected and blocked yesterday:
This graph shows the proportion of Viral e-mail which was detected and blocked yesterday:
If your own personal Anti Virus software has identified a virus that wasn't identified by the virus defininitions used by Zen Internet, you can submit these raw samples to ClamAV directly so that new virus outbreaks can identified quickly. To submit your raw virus sample please visit the ClamAV Web site (www.clamav.net) for further information.
