There's a number of viruses/worms in the wild that are programmed to 
exploit various M$ vulnerabilities:

80  - IIS WebDAV (MS03-007)and any number of other IIS vulnerabilities
135 - DCOM RPC (MS03-026)
445 - RPC locator (MS03-001) and Workstation service (MS03-049)
139 - Unpassworded NetBIOS shares

I'm not sure about the other ports, I *think* 1025 has something to do with 
MS RPC as well, but don't quote me on that.

What you are probably seeing, at least in the cases involving the ports I 
listed above, is one of the many W32.Gaobot (Symantec)[1] variants.
