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.
Read the analysis of W32/Klez-H.
