PC World reports that some messages appearing to originate from legitimate sources and asking recipients to click on a link to retrieve a virtual greeting card actually send users to Web sites that install malicious Trojan horse software on their computers.
The messages spoof the "From" addresses of legitimate companies like Blue Mountain Greeting Cards and contain subject lines such as "You have received a virtual postcard from a family member." In HTML-based email they can be difficult to tell from the real thing because links may appear to go to one address but take users to a different one when clicked.
Experts recommend verifying the legitimacy of URLs that appear in virtual card notifications, then copying and pasting them into your Web browser instead of clicking on them directly to avoid ending up at unexpected and potentially unsafe destinations. Read more...

Received email titled, “You’ve received a greeting from a family member!”
You are asked to click the link to retrieve your postcard. The site that this link accesses contains just one executable file, postcard.exe, that probably installs a Trojan horse virus on your computer.
It installs the trojan “downloader” virus on your pc – it did mine – get symantec’s intelligent updates – that will cure it!
This looks like it comes from Blue Mountain but it DOES NOT.
If you click on the link it does, however, take you to a page that downloads a Trojan virus to your computer called card.exe
The virus is JS/Psyme

I’ve had about 8 of these over the last 2 weeks. The first one I got kind of made sense because I had just been exploring a classmates website, card said I got a card from a classmate. I clicked on it, and fortunately my Avast anti-virus detected it immediately, and prompted me to quarantine it.
I’ve been getting 10-20 of these almost every day for weeks! I knew there was something wrong because I’m closing out the email address they’re coming to, so no one has been using it.
Also, only paid members can get your email address from Classmates…
