URL : http://www.us-cert.gov/current/index.html#msn_messenger_trojan US-CERT is aware of reports of a Trojan spreading via MSN Messenger. The Trojan arrives as a chat message that appears to contain an image file, that when opened, downloads and installs a Internet Relay Chat Bot. These messages may appear to come from a known contact.
US-CERT urges users and administrators to take the following preventative measures to help mitigate the security risks: Install anti-virus software, and keep virus signature files up-to-date.
