Malware is a definition for malicious software. Basically, it is any kind of a program or a script that have intentions to access your computer in unauthorised way and collect your personal information, gain control over your system, display advertising or redirect you to websites with questionable reputation. There is a thin line between malware and legitimate software and that line is called PUP (potentially unwanted program). While it\'s clear what is legitimate software and what is malware, definition of PUP can be confusing.

In regard to distribution methods, malware can be of 4 kinds - installed by hackers or other malware (other malware), installed due to various vulnerabilities (worms), attached to legitimate programs (viruses) or installed by user himself while pretending to be something else (trojans).

Even though all malware is aiming to make money one way or another, strategies to reach the goal can vary a lot. There are several main groups:

  • Adware, such as popups or hijackers aim to make money by displaying advertisements. Browser hijackers belong to this generic group too
  • Spyware is either selling or using your private information - it\'s common for banking trojans and keyloggers.
  • Probably the most threatening type of malware - scareware is trying to make money by forcing users to pay directly. For instance, ransomware hijack files and demands a ransom to be paid in order to unlock them or rogue antivirus which tricks users to pay for services that are not actually legitimate.
  • Other types like Crypto miners are using your PC resources or sell their services for other computer parasite makers.
