WHAT IS TROJAN

Trojan just like every other malwares such as virus and worm are malicious software that disguises as legitimate program or file online which is extremely dangerous and can disrupt a system,network or computer.

They are software program designed by cybercriminals with the only purpose and main objective of wrecking havoc in a system or network where it gain access into.

The Trojan is capable of damaging, deleting, stealing and disrupting files and documents in a whole system or network once it manage to instill itself in the computer or system.

It is often difficult to know a file or application containing Trojan horse or virus from a legit file or application online because it disguise itself as a bona fide document or appliancation whereby tricking users to download and install it on their device.

Once the app or file is downloaded or the link is cliked,this automatically means that the Trojan malicious code has been installed and it has also succeeded in executing t codes on the device and it can now begin to carry out the function of which it was designed for, causing damage!

The Trojan is referred to by many as Trojan horse or sometimes Trojan virus but factually speaking,none of this title is applicable to it.
This is because,virus can execute itself and also replicate or disseminate itself in a system or network while Trojan cannot.
Trojan depend on the user for it code execution process and operation.

Nevertheless,that isn't of Paramount importance right now,wether your prefer Calling it Trojan horse or Trojan virus,it is only important that we know how Trojan works and operate.

HOW DOES TROJAN WORKS

Think of Trojan as an impersonating software program,files,apps or document that disguises as legitimate document or file to be downloaded,open or clicked on because that is it operating mechanism.

Most times,they come in form of emails message with attachment directly from cybercriminals which will encourage the user to click on certain link in order to view the content in the attachment.

This link is a trap and once a user falls for the bait by clicking unknown link on email, downloading parody app unknowingly,opening and downloading files which contain this Trojan virus ignorantly,the trojan will quickly install itself in the system or computer.

And as soon as it installs itself In the computer and start to execute it codes,the malware will begin to disseminate into other files in your computer and in turn damage the whole system.

The function of Trojan in a system or computer varies as they are designed to perform different distructive operation in an infected computer,but trust me,you don't want to experience any of them.
