W32.HLLW.Polybot is a worm that attempts to spread through network shares that have weak passwords and allows attackers to access an infected computer using a predetermined IRC channel.

The worm uses multiple vulnerabilities to spread, including:

The DCOM RPC vulnerability (described in Microsoft Security Bulletin MS03-026) using TCP port 135.
The RPC locator vulnerability (described in Microsoft Security Bulletin MS03-001) using TCP port 445.

Virus Definitions released after February 27, 2004 and before March 19, 2004 detect this threat as W32.HLLW.Gaobot.gen.
