Beware Adobe Software Upgrade Notification - malware attached!

Cybercriminals have widely spammed out a malware attack posing as upgrades for Adobe Acrobat Reader and Adobe X Suite Advanced.
The emails, which pretend to come from Adobe, have a ZIP file attached which contains a version of the Zeus Trojan horse, designed to steal banking information from compromised computers.
The risk is that less technical-savvy computer users might believe the email is legitimate, and be tricked into installing malware onto their computer thinking that it is an official Adobe update.

Adobe Systems Incorporated,
Each email is slightly different, incorporating different reference numbers in the subject line, attached filename and message body. But the samples seen so far by Sophos all carry malware in the file "Adobe Systems Software Critical Update Dec 2011.exe" contained within the ZIP.
Computer users need to learn that Adobe never sends up software updates as an email attachment, and any legitimate upgrades should always be downloaded from Adobe's own website. It's trivial for a malicious hacker to forge an email header to trick the unwary into believing an email has been sent from someone else - so just because it claims to be from Adobe, doesn't mean that it was sent by them.
