Hi all,

My ZoneAlarm log is showing entries that have a Source address of
127.0.0.1 ! There are a number of ports being tried e.g. 1331, 1487,
1524, 1660, 1835, 1891, 1908, 1914 and 1991.

This only happens when I am connected to the internet (I'm on a dialup BTW).

Screen grab from ZoneAlarm here if anyone is interested (190Kb):

(my machine is called "pbw2k")... its running Windows 2000.

Should I worry about this?

Thanks in advance,

Peter.
