it seems like i caught a trojan but i'm running a firewall and the only special thing i've done is registering my nick.
what could i do to remove it.(i'm running slackware 9.0)

Your machine may have been infected by trojan horse which advertises one of several websites on DALnet. You should run a full scan of your system using a recently updated virus scanner or a dedicated anti-trojan package such as Swat-It to detect and if necessary remove the trojan. When you have done this, wait for the ban to expire then reconnect to DALnet.


How a windows trojan/virus could do that on Linux puzzles me.
