The W32.Sobig.F@mm is one of the most successful viri since LoveBug, so I just thought I'd post some info on it (from the Symantic site), to warn everyone:

-------------------------------------------------------

W32.Sobig.F@mm

W32.Sobig.F@mm is a mass-mailing, network-aware worm that sends itself to all the email addresses it finds in the files that have the following extensions:

.dbx
.eml
.hlp
.htm
.html
.mht
.wab
.txt

The worm uses its own SMTP engine to propagate and will attempt to create a copy of itself on accessible network shares, but fails due to bugs in the code.

Email Routine Details
The email message has the following characteristics:

From: Spoofed address (which means that the sender in the "From" field is most likely not the real sender). The worm may also use the address admin@internet.com as the sender.

NOTES:
The spoofed addresses and the Send To addresses are both taken from the files found on the computer. Also, the worm may use the settings of the infected computer's settings to check for an SMTP server to contact.
The choice of the internet.com domain appears to be arbitrary and does not have any connection to the actual domain or its parent company.

Symantic have also created a small removal tool, which can be downloaded here:

Just make sure your AV s/w has the latest virus definitions file, and you'll be fine (19/8/03 for NAV)

I've had it this morning. I checked one of my hotmail accounts and it was full of returned emails that I'd supposedly sent to a total stranger that had bounced back as they had a virus. My other hotmail account was not affected, nor was the computer I use at work (where I access the hotmail from). Odd that only one email account has been affected.
