用Ubuntu测试结果:
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.
At Risk!
Warning!
The test found visible port(s) on your system: 21, 23, 80, 137, 138, 1080, 3128
Recommendation:
Install personal firewall software. PC Flank recommends Outpost Firewall Pro.
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.
At Risk!
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.
Anti-trojans to consider are: The Cleaner, PestPatrol or Tauscan.
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.
Browser privacy check
The test checked if your web browser reveals any private information while you visit Web sites.
Usually such information is: the last site visited, your locale and who your Internet Service Provider is.
Danger!
Danger!

Recommendation:
We advise you to get personal firewall software.
If you already have a firewall program adjust it to block the distribution of such information.
