strange cgi-bin entry

[Nikolai Alexandrov <voyager123bg () gmail com>]

Hello out there, i want to ask you about strange entry i noted in my 
/cgi-bin directory...
ls -la
lrwxrwxrwx  1 root root 10 2005-07-08 14:11 AAA.BBB.CCC.DDD.cgi -> 
AAA.BBB.CCC.DDD.cgi

where AAA.BBB.CCC.DDD is a real ip address. I removed the link, and am 
pretty sure i didn't created it... It is the only entry in the 
/cgi-bin.  My question is: Could this mean my box is compromised? And if 
so... what should i do next? (reinstall is not a good answer in my case) 
Thank you in advance.

ps: I nmaped the questioned host (from outside), and no unnknown  (open) 
ports were found. Also netstat -nta did not show anything unusual. 
Logcheck also seemed normal (but if the host is compromised i know i 
cannot trust  the software I run on the same host).
