A software that installs on your computer without your consent is commonly referred to as malware. This term encompasses various types of malicious software, including viruses, spyware, and adware, which can compromise your system’s security and privacy. Protecting your computer from malware involves using antivirus programs, keeping your system updated, and practicing safe browsing habits.
What is Malware and How Does It Work?
Malware is a broad term used to describe any software designed to harm, exploit, or otherwise compromise the data and functionality of a computer system without the user’s knowledge or permission.

- Worms: Unlike viruses, worms can spread without user interaction.
- Spyware: This software collects user information without consent.
- Adware: It displays unwanted advertisements, often tracking user behavior.
- Trojan Horses: Disguised as legitimate software, these can open backdoors for other malware.
