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:
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
