Understanding Malware and How It’s Downloaded

Your computer has been running really slow lately, and pop-ups are polluting your screen. Suddenly, it crashes for no reason. What’s causing your computer to act out? The answer: Malware. 


What Is Malware?

Malware, short for malicious software, is software designed to damage your computer, server, or network. It can show up in many different forms; however, there are 9 kinds of malware that are the most common:

  1. Virus. The most common type of malware, a virus is a piece of code that is able to copy itself and infect programs on your computer. Viruses target specific files to destroy your data.
  2. Worm. This standalone computer program replicates itself and uses the computer network to spread to other computers. Worms cause harm to the network as a whole rather than individual files.
  3. Trojan Horse. Appearing as a legitimate program, trojan horses are programs that hackers use to gain access to a user’s system. Once downloaded, trojan horses give cyberthieves access to alter your data. 
  4. Spyware. This software sneaks into your computer and steals your internet usage data and personal information. It shares the data with spyware gatherers who sell your information.
  5. Ransomware. Blocking access to your computer system, this malware refuses to give back access to your system until you have paid a certain amount of money. 
  6. Rootkit. This collection of computer software gives an unauthorized user access to your computer system. The user is then able to gain control of your system without the software being detected. 
  7. RAT. Downloaded invisibly, RATs give intruders administrative control to do just about anything on your computer. This includes accessing personal information, recording a webcam, deleting files, and more.
  8. Adware. This unwanted software is designed to serve you advertisements whenever you’re using your internet browser. When downloaded, these programs carry out all sorts of unwanted tasks.
  9. Keyloggers. Often referred to as keyboard capturing, keyloggers record the action of every key pressed on the keyboard. This gives hackers the ability to collect passwords and other confidential information.
