This Valentine’s Day you could be looking for love in all the wrong e-mail — and, while it might not break your heart, it could shut down your computer for a day.

A particularly obscene and nasty-minded piece of virus email is floating around this season of love and romance, according to Vancouver-based virus and spam experts Sophos.

It has the subject line “First Love Story” and contains an attached file called FirstLove.vbs.

Click on the attachment and you won’t see anything happen, Sophos security analyst Dominic Wild said Friday.

However, on Feb. 14 the virus — the new VBSWG-D worm — will display a message that says “Happy F***ing Valentine . . . !!!”

After that it will send itself to everyone on your contacts list and then shut your computer down.

For the rest of Valentine’s Day the virus will continue to shut your computer down every time you start it up.

“The payload has a delay, so its not actually until Monday that they’ll actually see the message appear,” said Wild.

Another Valentine’s Day email, said Wild, carries the Kipnis-H worm and has “Happy Valentine’s Day” in the subject line. The body reads: “With the coming of Valentine’s Day! I very much love you.”

Click on the Valentine.exe attachment and the worm turns off all your anti-virus protection, installs a backdoor trojan which allows cyber-criminals to control your computer to send spam email and sends itself to all your contacts.

“If you see an e-mail, even if it’s promising love at this time of year, try not to succumb to it,” said Wild. “It’s important to just delete the mail.”

Also, said Wild, with the arrival of Valentine’s Day, as with most holidays, there will a definite spurt of spam messages like “FREE Valentine’s Day Chocolates” and “Don’t wait — 15% Off All Valentine Fresh Flowers lestrunum” and “Valentine’s Day Gifts for FREE*”.

“We’re expecting another spike this weekend,” said Wild. “The weekend seems to be a prime target for spammers who know people are at home and looking at their e-mail boxes.”

Wild said that while the messages may be from legitimate companies that will actually deliver the goods advertised, it only encourages spammers to reply to them.

On a lighter note, Nokia has announced the availability of a cellphone shell that allows users to paint romantic (or other) messages that appear to hang in the air.

Available from Rogers Wireless, the Xpress-on Fun Shell, uses an array of LED lights to paint messages like “I love you.”
