Found a new sort of worm, at least I didn't find any information about this on any securitysite;
Creates a registry entry \HKEY_CURRENT_USER\Software\Microsoft\Search Assistant\ACMru\5603 and adds a file called "umcss.exe" to C:\windows(winnt)\system32. The exececutable spawns a connection to a irc-server called apollo.uplinkearth.com at port 6667. I'm asuming it's sitting in a channel there to create a DoS at a specific date or to give the owner of that irc-server problems.
it also adds a line in mirc.ini telling it to load a script called custom1.mrc, which adds a "on join" to remote, sending several messages to channel visitors, including one with the URL above.
