Klez Worm hitting hard
A few months back you may remember reading about a virus warning for the Klez.E worm, a worm that exploits a well known security hole in Outlook Express (shocking as that may seem). Well it appears that the worm has evolved a bit and is now spreading very quickly under the name of <a href="http://email@example.com">Klez.H</a>.
The <a href="http://firstname.lastname@example.org">original virus</a> attempts to disable anti-virus programs, and also destructivly overwrites files on the infected system. This new variant spreads has the ability to spread via email or via network shares.
The icing on the cake is not the speed at which the virus is spreading, nor is it the fact that it exploits an <a href="http://www.microsoft.com/technet/treeview/default.asp?url=/technet/security/bulletin/MS01-020.asp">already well known security vulnerability</a>. Once a computer has been infected, the virus has a scheduled routine that begins to overwrite files on the infected systems hard drive with random content. Data files overwritten by this virus typically cannot be recovered except from a backup copy of the same file.
So take some time out of your day, make sure your anti-virus definitions are up-to-date, virus scan your system, and do a comprehensive backup. None of these routines are fun, but they are all much more fun then trying to rebuild your lost data files.
