thing can guarantee the security of your computer 100 percent. However, you can continue to improve your computer's security and decrease the possibility of infection by consistently following these guidelines.
The Advancement of the Keylogger

A keylogger is a program that runs in your computer's background secretly recording all your keystrokes. Once your keystrokes are logged, they are hidden away for later retrieval by the attacker. The attacker then carefully reviews the information in hopes of finding passwords or other information that would prove useful to them. For example, a keylogger can easily obtain confidential emails and reveal them to any interested outside party willing to pay for the information.

Keyloggers can be either software or hardware based. Software-based keyloggers are easy to distribute and infect, but at the same time are more easily detectable. Hardware-based keyloggers are more complex and harder to detect. For all that you know, your keyboard could have a keylogger chip attached and anything being typed is recorded into a flash memory sitting inside your keyboard. Keyloggers have become one of the most powerful applications used for gathering information in a world where encrypted traffic is becoming more and more common.

As keyloggers become more advanced, the ability to detect them becomes more difficult. They can violate a user's privacy for months, or even years, without being noticed. During that time frame, a keylogger can collect a lot of information about the user it is monitoring. A keylogger can potential obtain not only passwords and log-in names, but credit card numbers, bank account details, contacts, interests, web browsing habits, and much more. All this collected information can be used to steal user's personal documents, money, or even their identity.

A keylogger might be as simple as an .exe and a .dll that is placed in a computer and activated upon boot up via an entry in the registry. Or, the more sophisticated keyloggers, such as the Perfect Keylogger or ProBot Activity Monitor have developed a full line of nasty abilities including:

* Undetectable in the process list and invisible in operation
* A kernel keylogger driver that captures keystrokes even when the user is logged off
* A remote deployment wizard
* The ability to create text snapshots of active applications
* The ability to capture http post data (including log-ins/passwords)
* The ability to timestamp record workstation usage
* HTML and text log file export
* Automatic e-mail log file delivery

All keyloggers are not used for illegal purposes. A variety of other uses have surfaced. Keyloggers have been used to monitor web sites visited as a means of parental control over children. They have been actively used to prevent child pornography and avoid children coming in contact with dangerous elements on the web. Additionally, in December, 2001, a federal court ruled that the FBI did not need a special wiretap order to place a keystroke logging device on a suspect's computer. The judge allowed the FBI to keep details of its key logging device secret (citing national security concerns). The defendant in the case, Nicodemo Scarfo Jr., indicted for gambling and loan-sharking, used encryption to protect a file on his computer. The FBI used the keystroke logging device to capture Scarfo's password and gain access to the needed file.


Surfing the Web Anonymously - Questions to Ask

When you surf the web it is possible to learn information about you even when you don't want to advertise who you are. This is true even if your system contains no virus or malware software. Specifically information that is easily available online includes your IP address, your country (and often more location information based on IP address), what computer system you are on, what browser you use, your browser history, and other information. It gets worse. People can get your computer's name and even find out your name if your machine supports programs like finger or identd. Also, cookies can track your habits as you move from machine to machine.

How do people get this basic information about you?

When you visit another web site, information about you can be retrieved. Basically, information is intercepted and used by others to track your Internet activities.

How do you stop this from happening?

First of all, it is possible to serf the web anonymously and thereby stop leaving a trail for others to find. Note that this is not fool-proof, but it makes it much harder for people to know who you are. There are products called anonymous proxy servers that help protect you. The anonymous proxy server replaces your Internet address for its own. This has the effect of hiding your IP address and making it much harder for people to track you.


How do I get an anonymous proxy server?

There are many vendors who sell anonymous proxy servers. There are also free proxy servers available to you. Two such products are ShadowSurf and Guardster. Guardster (http://www.guardster.com/) offers various services for anonymous and secure access to the web, some paid as well as a free service. ShadowSurf (http://www.shadowsurf.com/) ShadowSurf provides anonymous surfing at their site for free. Go to it and you will find a box to enter a URL that you want no one to track. There are many others, but here are two that are frequently used.

Another interesting product, given the recent news about the Google search engine filtering its findings for the Chinese government, is Anonymizer (http://www.anonymizer.com). This company, among others, recently (Feb 1st, 2006) pressed that it "is developing a new anti-censorship solution that will enable Chinese citizens to safely access the entire Internet filter-free" (http://www.anonymizer.com/consumer/media/press_releases/02012006.html).

Does an anonymous proxy server make you 100% safe?

No. Still, you are much
