Understanding Malware and its Impact on Windows 11

The term "wirus" is a colloquial term often used to describe malicious software, more formally known as malware. Malware is a broad category encompassing various types of software designed to harm or gain unauthorized access to computer systems. Windows 11, like any operating system, is susceptible to malware attacks, and understanding these threats is crucial for maintaining a secure and functional system.

Types of Malware Targeting Windows 11

1. Viruses: Viruses are self-replicating programs that can spread from one computer to another, often attached to files or emails. They can corrupt data, damage files, and even compromise the entire system.

2. Worms: Worms are a type of virus that can spread autonomously through networks, exploiting vulnerabilities in operating systems or applications. They can replicate themselves rapidly, consuming network bandwidth and potentially crashing systems.

3. Trojans: Trojans are disguised as legitimate software but contain malicious code that can steal data, install other malware, or grant remote access to attackers.

4. Spyware: Spyware is designed to collect personal information without the user’s knowledge or consent. This information can include browsing history, keystrokes, passwords, and other sensitive data.

5. Ransomware: Ransomware encrypts a user’s files and demands payment to decrypt them. This type of malware can be particularly devastating, as it can hold critical data hostage and disrupt business operations.

6. Adware: Adware displays unwanted advertisements on a user’s computer. It can be intrusive and slow down system performance.

7. Rootkits: Rootkits are designed to hide their presence and grant attackers persistent access to a compromised system. They can be difficult to detect and remove, making them a significant threat.
