First of all, computer virus and trojans together with worms and bots are all identified as classes of Malicious Software or the so-called MALWARE. Malware is a code or software that is developed to damage, steal and corrupt files or systems.
Viruses or computer virus works by inserting a copy of itself and becoming part of a program. It easily spreads from one computer to another through network, USBs and the like. Mostly, theses viruses are in executable file which is the black .exe square appearing on flash drives. However, these viruses won’t be able to speed if the use do not run the host file or program, that means once the host is executed, viruses automatically and enthusiastically spread. It copies itself and spreads all over the system.
A Trojan is another type of malware which was named after the wooden horse the greeks used to infiltrate Troy. It is a very harmful software that looks legitimate. Typically, users are tricked to loading and running/installing file in their systems. Once it is activated, it attacks the host and most things one can see are popping up windows or chasing desktops. IT also damages the host by deleting and stealing datas and/or activating or spreading viruses. One thing you must know that Trojans do not reproduce, it only spreads though user interaction such as opening email attachment and executing a malicious file from the internet.
