Can Avast detect the Valentine bug?

I accidentally opened a junk mail while trying to open a mail above it, I just mis-clicked. This mail said something about a “Valentine Postcard” and contained a junk poem and a link to “PostCard.exe”. I did not click on the link. Not more than three minutes after opening that mail, I started noticing emails in my inbox, mostly from Yahoo mail server bouncing back the emails from addresses that were invalid. I checked out my sent box and noticed three mails, which I did not send, addressed to one Yahoo address in the “To” box and every address I sent mail to in the “Bcc” box. Weird, because I didn’t click on the “PostCard.exe” link yet my computer is responding as if I did and the worm has infected my computer. This continued for most of the day, me clearing out my inbox and sent. Now everything seems to be alright. I did an Avast scan and everything came up clean. I ran some anti-spyware apps, Ad-Aware and a-squared, and both came up clean. I don’t get it.

Remeber, different av company may have different names for the ame virus.

I believe it’s the Dref-AB worm but I only know that because I read it somewhere so I’m not sure if that’s what the link the in mail is pointing too. I didn’t see it in the virus list.

I found an alias Email-Worm.Win32.Zhelatin.ab
