Although the computerized version of the Trojan horse won't generate the same level of destruction that its original counterpart did, it may still cause a lot of problems to a computer user or to an organization.
The intention of every cracker is to exploit their skills in order to obtain a benefit from it. So, if he has infested your computer with a Trojan, he will want something out of it.
One of the most common uses of Trojans is to access the accounts of a user. It can be a bank account, credit card account or an email account. All of them contain important information about your life and finances. And that is what a cracker is craving for. Before you know it, your credit card could be used for buying things at the other side of the world.
There are several types of free backdoor Trojans. After all, there are thousands of crackers out there, trying to make a living. One of the most common ones is the Back Orifice. It appeared in 1998 and a newer version was launched in 1999, known as Back Orifice 2000.
Other known programs are NetBus, SubSeven, Downloader-EV and Pest Trap. All of them have been designed for picking up data and information from innocent users who don't know what is happening inside their computers.
How to Remove Backdoor Trojans?
How to remove backdoor Trojans is one of the biggest questions among computer users. After all, these pesky pieces of software can become more than a nuisance. If you don't want to pay a lot of money to a computer technician, then it is in your best interest to learn free removal of backdoor Trojans. That is, by yourself.
Now that you know that caution should be your highest prerogative, then you should take the next step: update all your software. That includes your operating system, office suite, antivirus, firewall and anti-spyware. They are like the pillars of a structure. If one of them isn't adequately fixed to the ground, the others will not be able to withstand the weight.
Remember that when we mention an actualized operating system, it means one of the latest versions of the OS. Since it is highly probable that you are using Windows, assure yourself that you are using, at least, Windows XP Service Pack 2. If you have installed Windows ME or Windows 98, buy a version of Windows XP right now. It isn't difficult, just make a call to Microsoft or go to your nearest computer store.
The second and final step is to stop downloading unsecured content. That includes files from P2P programs like Emule or BitTorrent. The majority of files from these sites have been altered in one way or the other. You must be very careful with them.
Like it or not, we are always going to live with Trojans; backdoor entrances are being reported everyday, especially in Microsoft Windows. So, if you don't want to spend an entire evening trying to delete backdoor Trojans, then you should assume your responsibility as a computer user and take the proper countermeasures. If not, you will suffer from the consequences.
