Huh. Checking my Hotmail account tonight, the McAfee virus scanner bounced a message I'd allegedly written, to someone in Australia that I've never heard of, informing me it possibly contained the sobig.f worm.
To tell the truth, I've never been really paranoid about, or troubled with, viruses. I keep my virus checkers up to date, regularly scan Microsoft for security patches, never open attachments, etc.
Apart from the usual spyware, I've never been hit with anything except for one Trojan horse which I caught before it did any damage. So I don't get too caught up in the media hype.
I don't seem to be infected, as far as I can tell.
I did a bit of research on sobig.f and this is how it spreads:
1. Person A's computer gets infected
2. Sobig.F harvests email addresses fron that computer, including addresses for persons B and C
3. Sobig.F sends email from A's computer, using a "From:" address of person B, and a "To:" address of person C.
4. Person C's antivirus software notices that the email "from" person B is infected, so C emails B to warn him or her.
5. Person B scans his or her computer and finds no virus; person B is very confused.
Well, Person B is usually very confused, but I blame it rather on excessive alcohol intake.
If you do get an email from Person B (that's it! I'm changing my nick!), I didn't send it, unless I did, in which case it's safe to open the attachment. Or maybe not.
I hope I've made myself perfectly clear.
