Spammers started taking advantage of the Valentine holiday early this year and McAfee researchers started seeing Valentine e-cards with malware and spam emails containing love messages "Deeply in love with you," and "Only you in my heart," as early as 22 January – and they've been increasing steadily ever since.

McAfee has also seen fake online dating profiles designed to scheme people out of money, as well as Nigerian love scams targeted through spam e-mails. While these kinds of romance related scams have been around for a while, they're becoming more personal and targeted.
The love bug virus reminded us nine years ago that not all love-related messages are worth opening, even on Valentine's Day.
McAfee is tracking Valentine's spam to be between 1% and 2% of the total e-mail sent on a daily basis.
