Security experts have advised emailers to make it their new year's resolution to take computer security more seriously in 2008.
The warning comes as hackers spread new versions of the Dorf worm (also known as Storm) disguised as Happy New Year e-cards.
Rogue emails contain links to websites containing malware, and have used a wide variety of seasonal subject lines, including: A brand New Year 2008, Blasting New Year 2008, Dance to the New 2008 Year tune, Happy New Year 2008 to the one I love, New Year 2008 Wishes and The New Year has arrived.
Previously, the worm spread via emails linking to an apparent Santa Claus-themed striptease. Once the worm has infected a computer it lets others access the computer, downloads code from the internet and reduces a system's security.
Graham Cluley, senior technology consultant at Sophos, said: "Many people will be returning to their desks this morning after a lengthy break for Christmas and New Year to a brimming bundle of unread emails."
"The danger is that the holiday hangover will make them less careful about which messages they click on. Anyone clicking on a mystery weblink or an unsolicited email attachment is putting their computer at risk of being taken over by hackers for illegal ends. Everyone needs to make their New Year's resolution to take computer security more seriously in 2008."
