Cybercriminals are spreading a malicious Trojan horse under the guise of an update to Skype, e-mail security firm MessageLabs said Monday. The Trojan horse, a variant of IRCbot, arrives in an e-mail purporting to be an update to Skype, the popular Internet telephony application. Once opened the malicious software displays a phony installation error message. It then blocks access to security updates and installs a back door on computers, MessageLabs said in a statement.
