It is called a Trojan to an informatics’ virus or malicious program that is capable of storing in the computer allowing access to extern users, through a local net or from the Internet, with the objective of getting information. It is a small program stored within an application, an image, a music file or any other apparently-innocent element, that installs in the computer when you execute the file where it is in. |

Many Trojans remain hidden and the antivirus or anti trojans don’t detect them, but other tomes, being installed, does a performance as it realized a useful function, but internally does other tasks that the user doesn’t know about, just like the Troy Horse that the Greek gave the Trojans.
Most of the times, the Trojan is used to spy, using the technique to install a software of remote access that allows to monitorize what the legitimate user of the computer is doing and, for example, capture the keyboard’s pulses so that it can obtain the passwords or any other sensible information.
The best defense against the Trojans is not to execute anything that came from an unknown origin and to keep the antivirus software updated. It is recommended to also install an anti Trojan software, one of those free versions, even though some of them are a Trojan itself.
Another way to detect them is inspecting frequently the list of active processes in the memory to look for strange elements, to check the unnecessary disks accesses, etc.
To maintain the computer safe, we recommend you the three golden rules:
1. Use a good antitrojan application that provides regular updates. Use the software regularly and keep it updated.
2. Use a good antivirus application, that offers regular updates of virus definitions, use the software and keep it updated.
3. Keep your operative system updated with the security patches. The details of the security updates of Microsoft are in the site. |
