Attackers are increasingly using greeting card scams to foist trojans on the unsuspecting. Fortunately, there are some tell-tale signs and tips to follow that can help you avoid becoming a victim.

Be extra suspicious if (a) the greeting card doesn’t
address you by name; (b) the card sender’s name isn’t included in the
body of the email or the name isn’t familiar; and (c) it’s not a
holiday, a birthday, or any other occasion that might warrant a card.
If the card requires that you install a special viewer or tries to
download a file to your system, treat it like a trojan. Cancel the
download and scan your system with up to date antivirus software.
