Yawmo is a trojan that collects system details and user sensitive information, and shares all this data via Winny and Share file sharing networks using installed peer-to-peer applications. The parasite also drops a backdoor, which provides the attacker with unauthorized remote access to the compromised computer. The intruder can steal user confidential data and control the system. Yawmo may suddenly launch Windows Media Player. The trojan runs on every Windows startup.
