I was catching a lot of these Sober.O viruses yesterday. They are so fresh my anti-virus definitions were not up to snuff in catching it.
Make sure your anti-virus software is fully up to date. This one is picking up steam pretty quickly.
What it does is send you email messages with an attached ZIP file. The message contents say something to the effect of:
Account and Password Information are attached!
This is an automatically generated E-Mail Delivery Status Notification.
Mail-Header, Mail-Body and Error Description are attached
What’s especially tricky is that it signs the email with what looks like your own anti-virus software stamp of approval:
*** Attachment-Scanner: Status OK
*** “yourcomputerminute” Anti-Virus
1. don’t open any Zip files that you may have received since Sunday of this week.
2. Make sure your antivirus is up to date and verify this with your IT folks before you open any other zip files
