** I have recieved a report from my ISP that calendar script is listining on port 55555 **
It is not likely CalendarScript's programs but someone may have uploaded an application through CalendarScript, which is responsible. If you have installed anything older than the latest CalendarScript version (presently 3.21), you should upgrade or disable it immediately.
You (or your host) will have to track down and disable the offending script(s) as well.
