Another email virus (technically a trojan) is currently making the rounds. This one is an attachment to a message the subject "You've received a postcard" with the following text:
Good day.
Your family member has sent you an ecard from 123greetings.com.
Send free ecards from 123greetings.com with your choice of colors, words and music.
Your ecard will be available with us for the next 30 days.
If you wish to keep the ecard longer, you may save it on your computer or take a
print.
To view your ecard, open zip attached file.
The attached file is a zip file, named ecard.zip, and is 30KB in all samples CB Services has seen so far. This reduces to just over 22KB after decoding from email by saving to the drive in your computer.
This virus is, as of this writing, not detected by Norton, Trend Micro, or McAfee. (Click the thumbnail to see the full size results in a new window.)
This virus is quite new, and hasn't been fully analyzed. It may perform various actions to reduce the security of your computer, such as turning off firewall or antivirus software, or disabling automatic updates.
It appears that it is also related to rogue antivirus software, that will attempt to scare you into purchasing fake antivirus by claiming your computer is infected with numerous viruses. These "infections" are false positives.
