A Trojan horse virus is invading inboxes through a holiday greeting that claims to have pictures of women in sexy swimwear.
An email from someone named "Yoko" says: "Hello my dear!!! How are you? As I promised here's my bikini photos. I hope you will be love it! This is my humble gift for Christmas! See you later :)" Instead of Yoko, the sender signs off with, "Your love, Ciara."
Victims of the scam will also find a .zip file that contains what appears to be a bikini screen saver labeled as Bikini.scr. It's very encrypted and infected.
Emails from strangers should always be treated with caution and you should never download an attachment from someone you don't know.
