When people speak about worm and trojans they frequently say worms in place of trojans and vice verse, however, trojans and worms cannot be said interchangeably like that as they are different. The only thing that they have in common is that they are very harmful to ones computer.
Differentiation between Trojans and Worms
What Is a Trojan Virus?
A Trojan virus attempts to connect itself to a file so that as people share their files it spreads and multiplies, resulting in hundreds and thousands of people having the virus on their computer. There are different degrees of trojans viruses: Some may have minor effects and some may permanently damage one’s software or even hardware, that shall be discussed in much detail later.
A large number of trojan viruses connect to a executable file. What that means is that the trojan virus may be present on one’s computer but it can not cause any damage or even spread the files because the hazardous program has not run on the disk. In order for viruses to spread there has to be a human act, actually the spreading of the trojan virus is caused by human activity of running the program on to their disks but note that their activity is without any knowledge.
What Is a Worm?
Worms are alike to trojans in terms of design and are regarded as a sub-class of a trojan virus. Worms multiply and they do this even without human activity. Worms are able to commute from computer to computer without being sensed as it takes the lead on the file information transferring system.
The most hazardous feature of a worm is that one worm can make thousands of copies of itself and then it may send the replicas to one’s contact list of e-mails of which then causes a horrific effect.
