Update: As of 4:29pm Aug. 22, F-SECURE is reporting that all the computers SoBig is supposed to download from are offline, so it looks like the threat is neutralized at this point.

NOTICE 08/22: The SoBig email virus is expected to try to use infected machines to initiate a new attack today (Friday) and again Sunday between 3pm and 6pm EST. Infected machines will attempt to connect to the internet, download a program, and run it. At this time, it is unknown what the program is designed to do. Read more information from F-SECURE:

Currently the largest-spread virus in the world, "SoBig" is a worm that spreads via email. SoBig comes in the form of an email attachment that, if opened, can infect the computer and spread further. It mimics legitimate email addresses and can appear to come from a familiar source. The attachment has a size of around 70KB. Look for these kind of subject headings in emails you receive:

Thank you!
Your details
Your application
That movie

The attachment, typically, is named like one of these:

your_document.pif
document_all.pif
thank_you.pif
your_details.pif
details.pif
document_9446.pif
application.pif
wicked_scr.scr
movie0045.pif

If you receive such an email you're not expecting, delete it. Do not open the attachment. Follow the links below for:
