I played Nethack a lot on my Atari ST. Took me quite a while to figure out why I could never get past level 1. "You are blocked by a mysterious force!". The best way to keep viruses off your computer is always use diskettes with write protection on. Only remove the write protection when you actually want to write something to the diskette. It's just a small physical tab you slide to the side. The game magically started working one day when I moved it to a ramdisk on my new Atari STe with lots of memory. Turns out that Nethack needs to write Level 1 to disk before it can allow you down to Level 2 in the dungeon... What a wonderful error message? :-)
