Stop spam, viruses, and other unwanted e-mail before they get to your computer, using this powerful software. MailWasher Pro works directly with your e-mail server, exactly like your e-mail program does. But there is one important difference: you can tell MailWasher Pro to delete a message at the server, without downloading it or you can bounce an e-mail back to the sender so that it looks as though your address is not valid.
The Universal Plug and Play service (UPnP), which is installed and running in all versions of Windows XP — and may be loaded into Windows 98 and ME — essentially turns every one of those systems into a wide-open Internet server. This server listens for TCP connections on port 5000 and for UDP 'datagram' packets arriving on port 1900. This allows malicious hackers (or high-speed Internet worms) located anywhere in the world to scan for, and locate, individual Windows UPnP-equipped machines. Any vulnerabilities — known today or discovered tomorrow — can then be rapidly exploited.

The scan should take about 30 seconds to complete, if you encounter an error please refresh the web page.
HACKYOURSELF promises that no information obtained from the security scan will ever be given out to anyone except properly warranted law enforcement and within 24 hours will be deleted utterly.

Privacy & Security Advice for Home Users. This web site was set up first and foremost for the classes I taught at the University of Illinois -- see the Introduction: Why This Web Site? for more details on what the students did in those classes. To help my students understand the gravity of privacy and security problems on the Internet, I wanted them to gain an appreciation for what widely available malicious applications are capable of doing. Indeed, I even advised them to visit the web sites for Sub7, Back Orifice, and NetBus and check out the feature sets described on those pages. It's an eye-opening experience, to be sure -- and not just for my students. I've pointed a number of people to those web sites in order to reinforce the nature of the privacy and security threats that one faces on the Internet

This is not a security risk. If this disturbs you, please do not get scanned. This is a basic TCP/UDP port scan. The TCP
(full connect) scan starts first, and results are shown as ports are found.The UDP scan goes next and must complete,
before any results are shown.

This test checks Windows 95/98/NT for shares that may be unexpectedly accessible to intruders via the Internet.This threat exists not only for hosts permanently connected but also and perhaps, particularly for those temporarily logged into virtually any provider's dial-in pools via telephone or ISDN. We have proved that it is possible to scan those pools for active connections then compromise a connected computer over those phone lines.
Once you find out that you can test the security of your computer online, it makes a lot of sense. While on the Internet, your computer may have 65,535 "ports" open. If the ports are open, a hacker or script kiddie may call. There are many online test sites. You need to be a bit skeptical about which of them to rely on. As a rule of thumb, do not rely on a testing site provided by a company that wants to sell you a personal firewall.
Did you know that using and upgrading certain software packages can help improve the security of your PC? Here are three steps you can take today to begin improving the security of your computer.
When you use the Internet there are dangers around every corner. Viruses, malicious users, Trojan horses, Oh my! If these are just concepts to you, you are either lucky or well protected (or just un-connected). If these names trigger painful flashbacks to when your computer (and possibly your account balance) was rendered inoperable or compromised by one of the above, then join the club.
Either way, securing your computer against threats from the Internet is an essential step. If you do not, you will, at some point, regret it. Guaranteed.

The table shows examples of existing trojans and ports being used. The lower ports are often used by trojans that steals password and either mail the passwords to attackers or hide them in FTP-directories. The higher ports are often used by Remote Access trojans that can be reached over the network. If you find probes directed against ports normally not used, it may be someone trying to connect to a trojan inside your network. I hope this list will be of some help for you.

As the the threat of "spyware" and "adware" has escalated over the past few years, the number of "anti-spyware" scanners available on the Net has grown equally fast. At present there are over 100 anti-spyware scanners available for download -- some for free, some for pay. Spyware and adware are themselves complex enough to prove bewildering to most average users, however. So confusing in fact is the threat of spyware and adware that users often have trouble distinguishing effective anti-spyware scanners from less effective ones.
