Malware is malicious software that may include various types of code, programs, or scripts designed to damage computers, networks, mobile devices, or other electronic systems. These programs are typically designed to disrupt the normal operation of devices, gain unauthorized access to information, or otherwise damage the integrity of data.


Several types of malware are known:

  • Viruses: associated with infecting existing files and spreading through infected files.
  • Worms: Spread independently over networks, replicating and infecting other devices.
  • Trojans: They hide behind the appearance of legitimate programs but have hidden malicious functions.
  • Ransomware: Encrypts files on a device and demands a ransom to restore them.
  • Spyware: Tracks and collects information about a user’s activities without their knowledge.

What are the risks of malware?
