The term "malware" might sound like tech jargon, but it's something everyone with an internet connection should understand. Malware can corrupt files, steal personal information, and even hijack your system. In this beginner's guide, we will break down the types of malware you should be aware of and how to protect yourself.

What is Malware?

Malware is short for "malicious software," a term encompassing various harmful programs designed to compromise the security and functionality of computers and mobile devices.

The Most Common Types of Malware


Viruses attach themselves to legitimate files and spread when the host file is activated. They can corrupt data and hamper system performance.


Worms are self-replicating malware that spreads automatically, exploiting vulnerabilities in networks.


Named after the Greek myth, Trojans disguise themselves as legitimate software. They open a backdoor for hackers to gain unauthorized access.


Ransomware encrypts your files and demands a ransom to unlock them. It has gained notoriety for targeting both individuals and organizations.


Spyware covertly gathers your personal information, usually for advertising purposes but sometimes for more nefarious goals.


Adware is less harmful but equally annoying. It displays unwanted ads and can slow down your system.

Signs You Might Be Infected

  • Slower system performance
  • Unexpected pop-up ads
  • Files disappearing or being encrypted
  • Unauthorized system changes
