I don’t know where to post this, but I want to warn others of this trojan, whoever has skype. Under few days it has rampaged through millions.
Short story short: Do not click on links from text “lol is this your new profile pic? (link)”, it will even send translated version of your country sometimes.

Anyone who sends you those virus messages are infected people, who downloaded and launched virus .exe file, therefore, you can know if you are infected (if you send same messages to others).
