Tips to eliminate Trojan horses
Trojan horses. What are they and how to get rid of them?
Tips to eliminate Trojan horses:
Trojan horses or Trojans as they are commonly known as, have established themselves as a terrible plague that pretends to take our PCs down, this programs are capable of camouflage themselves in other programs we are downloading from some website; once we run the program, Trojans can infect our systems up to the point in which our computers are controlled from an unknown foreign user.
Most of the Trojans have as a goal to open communication back doors, such as TCP or UDP ports, others gather personal information, such as: our passwords, bank account numbers, credit card numbers, phone numbers, etc; some others just have the task of destroying personal information or the system’s information, but most of the Trojans are just in charge of spying and been able of controlling the victims computers without he or she been aware of this. These are the facts that distinguish a Trojan from a virus, its goal, because usually Trojans do not destroy, unless they have this property.
The intrusion way into our systems is much known for those who have already been infected by this program, the Trojan is hosted inside applications in websites from unknown origins, they could be images in gif format, music files (mp3, mov, mav), videos, programs, etc. Another method of infection is through e-mails; when we receive an e-mail with attachments from some unknown sender and open them, for been installed in the PC, the program runs as usual without been detected by the antivirus software, because, apparently it is running the applications we wanted, but what the Trojan is doing for real, is making our PCs vulnerable. This is why it is known as a Trojan horse, because it uses some sort of disguise, similar to the one the Trojan citizens let inside their forte, decision which led them to destruction.
By been able of making our PCs vulnerable, intruders can easily gather information from our computers, others just focus on performing destructive actions, however, each day intruders create new techniques and evolve with sophisticated applications, these Trojans open some backdoors which allow them to connect our equipment and control it with us been completely unaware of their presence.
Some precautions I would advise you to take in order to avoid these types of programs are: every time you open an attachment, be sure that the sender is from a reliable source and not an unknown contact, because infections via e-mail is one of the most common ways of intrusion to the systems.
When you configure your e-mail, be sure to deactivate the automatic gap for attachments, that way you can decide if you want to open them or not. Some e-mail customers have antivirus software that scans the attachments before they are opened, or can be synchronized with the antivirus software that you have installed in your PC. If your client does not offer this possibility, maybe it is time to purchase or download another one that does.
Check your operative system’s patches once in a while, because new failures are found every day on them, and keep your antivirus software updated against the new threats that will come every day.
Last but not least, avoid using peer to peer programs (P2P), such as E Mule, Kazaa, Limewire, Ares, I Mesh or G Nutella; because they usually carry Trojans while you are downloading files.
