What is Malware?

I have heard more frequently the word malware, but the question is “what is malware?”. I didn’t even know what that word mean until I made some research. According to the definition, malware is the abbreviation of “malicious software”, and it is considered as a malicious program that harms the functionality of a computer. Also, malware is composed by many other tools that harm the computer, such as viruses, Trojan horses, and worms. People often create these malware to steal information from the user, to modify it, or even to delete important data from the computer. These activities are made by the malicious programs without any permission.

it is possible to divide the kinds of malware depending on their characteristics and the way of how each one acts.

  • Virus: this one is the most common one. It has the name virus because it acts as in health, it spreads in the computer and spreads very quickly with malicious software. Virus infects other programs.
  • Worms: it is a type of malware that multiplies without any command or a specific action. Worms can be activated without any human interaction and it affects the performance of the computer.
  • Trojan horses: its name comes as in history. It appears to be a legit program until it is executed. While it is executed, malware is installed in the computer and can use malware’s functions.
  •  Spyware: this last one is the one that steals information from the user without any knowledge from him or her. It also watches the movements from the user to learn from him or her.

The following video explains the types of malware. I’ll recommend you to watch it.

 

It is known that the first tope of malware was a virus, it was called the Creeper virus and it happened in 1971. It was a virus that eplicated itself over and over. There are a lot of facts regarding malware. I found a video that shows 25 interesting facts about malware.

Malware isn’t the only one that makes people install stuff in order to get access to the computer. PUP is a another tope of program that makes toe user to think that the program is needed in order to get some features. PUPs are most of the time toolbars and they don’t execute malicious funtions. PUPs can be classified as malware when these installed fetures steal information from the user or when they are used to sky on people.
