1. Don't Let Sobig.f Fool You
The Internet worm Sobig.f has generated a global epidemic and many
computer users are confused by some idiosyncrasies in the behavior of
this malicious program.

>From the moment when Sobig.f appeared, many people received notification
about the worm from Internet Service Providers automatic anti-virus
filters. The auto-generated notification informed users that copies of
the worm have been detected in e-mail sent from their computers. At the
same time, the anti-virus software installed by the users did not detect
Sobig.f.

Kaspersky Labs warns users that Sobig.f includes a feature that
falsifies the Sender address. The worm inserts a fake Sender address
chosen at random from e-mail lists found on infected computers. On the
one hand, the worm uses this feature to hide its tracks and make it
difficult to pinpoint the source of infection. On the other hand, this
also discredits innocent users and confuses them by misinforming them
about the infection.

Therefore, Kaspersky Labs reaffirms that all versions of Kaspersky×
Anti-Virus will inform the user when the computer is infected with
Sobig.f if the latest anti-virus updates are installed. In this case
your computer is safe to use.

A detailed description of Sobig.f is available in the Kaspersky Virus
Encyclopedia at: http://www.viruslist.com/viruslist.html?id=2744146
