What is a Trojan?

A Trojan is a type of program that enables a hacker to intrude and make changes to your computer. It is a threat in disguise. Like the Trojan Horse popular in the Greek history, it appears safe (in the form of software program and e-mail attachment). But once opened, the Trojan may install itself on your computer and gain access without your consent.
Generally, the initial objective of a Trojan is to browse your hard drive to determine anything of worth such as credit card information, passwords, confidential documents, email addresses, confidential designs or pictures, or even calendar information regarding the user’s whereabouts. Once found to be a potential source, the intruder then gets inside and manages your files totally. The intruder can do the following: rename, create, delete, view and even transfer files to or from your computer.
Trojans will enable the intruder to open and close your CD-ROM drive, spam and gain control to your keyboard and cursor. Trojans can also use a program manager that will allow the intruder to install, execute, open or close any software programs. Indeed, it is big threat to security.

How does it affect your computer?

The business starts first by the user installing the Trojan itself. This is done by deceiving the user with a seemingly useful system enhancement or perhaps a free game containing Trojans. By installing a free game, for example, Trojan will be automatically installed too. Trojans can also come in common disguises such as files from unknown sources, e-mail attachment from unknown sources, and files from any online activity client like ICQ. Once contaminated by Trojan, any distant user will inevitably have free access. The dirty work then starts.
Other types of Trojans are: Remote Access Trojans, Mail Trojans, FTP Trojans, Telnet Trojans, Keylogger Trojans, Fake Trojans, and Form Trojans.

Protect your Computer from Trojans

Trojans can also be distributed as email attachments, or bundled with other software programs. You should always be wary of opening attachments and downloading programs from the Internet unless you are sure it is from a secure and trusted source. If possible, confirm with the sender.

What is a computer virus?

A computer virus is a set of computer codes that overwrites, replaces or attaches itself to some part of a program or operating system in order to make a copy (or copies) of itself. It comes with instructions that set off some task(s) that affect the infected computer. These may range from the comparatively harmless to really destructive. Some viruses display text or pictures, but other than that, they are relatively harmless. Others, reduce memory space, modify existing data, or use up CPU processing time. But the destructive ones may overwrite or destory all your files or even crash your hard disk!

How does a computer get a virus?

A virus can be introduced to a computer in various ways. It can be attached to any file or programs that you copy from floppy disks, or download from the Internet. While many viruses today spread through email, and they are released not only by opening the attachment but also by simply opening the email itself.

The virus can be activated the minute it is installed on your computer; but in many cases, it can remain inactive until you run or execute the program that contains it. You will not usually be aware of the presence of the virus, and may innocently spread the virus to others.

An ounce of prevention

A virus can do its dirty work on your personal computer or your network; but there have been many cases that a particular virus wreaks havoc on the entire world, severely compromising many corporate businesses and government functions. Thus, it is important to take the necessary precautions before it is already too late.

As the world gets connected with today’s intricate cyber world, viruses spread faster than ever. So when you notice that your computer is acting a bit weird or erratic, you should immediately scan for a virus.

Recommended downloads to prevent and delete Virusses

There is a way for unhonnest webmasters to add popups and other nasty stuff to almost every page you visit. With the use of an exploit they can hack your computer files and modifiy a very important one :

- Windows 98: c:\windows\hosts
- Windows 2000: c:\winnt\system32\drivers\etc\hosts
- Windows XP: c:\windows\system32\drivers\hosts

By editing this file they can steal traffic from any site they want, they can block your access to any site, or they can add advertising (popup(s), dialers) to them. To hack your hosts file cheaters only have to have you visit their page, be it a TGP or simply a thumbnailed gallery! You don’t have to click anywhere on the page, you don’t have to install anything, it is a very malicious hack; you will not even notice that a flaw in your computer settings has just been exploited…

Open your hosts file (it has no extention) with notepad or another text editor. It should contain only this line :

127.0.0.1 localhost

If you see other domain names below it, it has been changed illegally (unless  you added them yourself). Just delete everything but 127.0.0.1 localhost. Save the file and close it, and you should be fine again. If you are unsure, you can simply delete the file from your hard drive, it will be ok. I have heard that making your file read-only can protect you, but I am unsure.

Surfing internet is becoming quite risky nowadays. You often have to browse through many unwanted popup windows, decline repetitive dialers install programs, sometimes your start page is changed without your consent, or new bookmarks are added without you knowing it. Actually, it is getting worse to the point we are getting emails everyday regarding those problems from our surfers.

Your computer can be infected by programs called adware (unsollicited advertising), spyware (recording your surfing activity to sell your information). Those programs come from many sources, webpages can make you install them unknowingly, or bundeled with popular software like Kazaa or Divx can install them onto your computer.

Before going further, let us give you some information on our site, and explain you why Worldsex.com links are not totally free of the scamming stuff we just mentioned. Experimented surfers probably know this already, but if you are new, read this.

We provide links to galleries containing sex pictures, movies and stories. Some of the galleries are of our own, but the vast majority is not. Webmasters come to our site to submit their galleries, we review them, twice, a script checks them continiously, and if they are clean, we add them to Worldsex. The problem is: some webmasters just can’t live honestly and they change their galleries after they’ve been submitted to worldsex. They add popups, dialers, anything, but the worst of all: they can install trojans and control your pc from the outside. In the following articles I’ll try to give more information what you can do to protect yourself and how ou can get rid of any current problems
