Sophos users already protected against Klez-H

Sophos, a world leader in corporate anti-virus protection, has reassured its customers that if they have kept their anti-virus software up-to-date they are already protected against the latest variant of the destructive Klez worm.

Media reports have today warned of a new variant of Klez (known as W32/Klez-H, Klez.H, I-Worm/Klez.H or W32.Klez.H@mm) spreading across the internet, but users of Sophos Anti-Virus have been protected against the new variant since 7 February 2002.

The March 2002 (3.55) edition of Sophos Anti-Virus protects against the new Klez variant via its detection of an earlier variant, W32/Klez-G.

Sophos first issued protection against W32/Klez-G on 7 February 2002, and recommends all customers subscribe to the email notification service to be automatically informed when new in-the-wild virus threats emerge.

Computer users are advised to consider installing a patch from Microsoft which is reported to fix a vulnerability in some versions of Microsoft Outlook, Microsoft Outlook Express, and Internet Explorer. The vulnerability is exploited by W32/Klez-H and a number of other viruses.

Please read the instructions for removing W32/ElKern-C and W32/Klez-H.
