Question

describe the differences and similarities between viruses, worms, and Trojan horses. Provide an example of at least one of these and describe that damage that can be done when a person or corporation is infected.

Answer 1

Lets me make it clear actually what these are first and then we move to the diffrences and similarities

A computer virus connects itself to a program or record empowering it to spread starting with one PC then onto the next, leaving contamination as it travels. Like a human infection, a PC virus can extend in seriousness: some may bring about just somewhat irritating impacts while others can harm your hardware, programming or records. All viruses are joined to an executable record, which implies the infection may exist on your PC yet it really can't contaminate your PC unless you run or open the pernicious program.

A worm is like an virus by outline and is thought to be a sub-class of an infection. Worms spread from PC to PC, yet not at all like an virus, it has the capacity to go with no human activity. A worm exploits document or data transport includes on your framework, which is the thing that permits it to travel unaided.

A Trojan Horse is loaded with as much cunning as the fanciful Trojan Horse it was named after. The Trojan Horse, at first look will seem, by all accounts, to be valuable software yet will really do harm once introduced or keep running on your PC. Those on the less than desirable end of a Trojan Horse are normally deceived into opening them since they give off an impression of being getting true blue programming or documents from a honest to goodness source.

Now I will Focus on the differences between Viruses, Worms and Torjan Horses

On the basis of its mode of spread

A virus attach itself to an executable file and then require a human to propogate, a worm does not require a human action to spread,torjan horse does not replicates itself and require human input to take into action.

• Unlike viruses and worms, Trojans do not reproduce by infecting other files nor do they self-replicate.
• Worms are extremely dangererous, because they can replicate themselves so successfully and do major damage.
• viruses are merely annoying and slow down your PC.

similarity is that they all are malicious programs that can cause damage to your computer.
