W32/Rbot-TV is a worm which attempts to spread to remote network shares. It also contains backdoor Trojan functionality allowing unauthorised remote access to the infected computer via IRC channels while running in the background as a service process.
W32/Rbot-TV spreads to network shares with weak passwords and by exploiting the LSASS(MS04-011) vulnerability.
W32/Rbot-TV can also download and execute remote files on the infected computer and flood other computers with network packets.
Sophos's anti-virus products include proactive protection technology, which can defend against new threats without requiring an update. Sophos customers have been protected against W32/Rbot-TV (detected as W32/Rbot-Fam) since version 3.88.
