What can I do to plug these holes with NIS 2002 Pro? These are the results
from PC Flank:

Check for vulnerabilities of your computer system to remote attacks
We have scanned your system for open ports and for ports visible to others on
the Internet. As a rule an open port means your computer is vulnerable to
attacks by crackers. They gain access to your computer and its files through
these open ports.

     Warning!
The test found visible port(s) on your system: 21, 23, 80, 135, 137, 138, 139,
1080, 3128
 

Recommendation:
Install personal firewall software. If you have already installed and are using
a firewall, check if it is set to make all the ports of your computer invisible
(hidden). If it is, then get new firewall software and redo this test.

Trojan horse check
The test scanned your system to find signs of a Trojan. If a Trojan horse is on
your computer a cracker can access your system's files and your personal data.

     Warning!
The test found visible ports on your system: 27374, 12345, 1243, 31337, 12348.
The following Trojans use these ports: SubSeven, NetBus, SubSeven, Back
Orifice, BioNet
Although these ports are visible, they are not open, so your system is not
infected. However, having visible ports on your system means your computer can
be "seen" over the Internet. This makes it very easy for skillful intruders to
explore your system.
 

Recommendation:
Install personal firewall software and use an anti-Trojan program. If you have
a firewall, check if it is set to make all your computer ports invisible
(hidden). If it is, then it failed miserably. Replace it and redo this test.
