Understanding Viruses and Malware
Before diving into the methods for removing viruses, it’s essential to understand what they are and how they can affect your laptop.
What Is a Computer Virus?
A computer virus is a malicious software program that, when executed, replicates by inserting copies of itself into other computer programs, data files, or the boot sector of the hard drive. Like biological viruses, computer viruses can spread from one computer to another, often without the user’s knowledge and can cause a range of malicious activities.
Types of Malware
Malware is a broad term that encompasses various types of malicious software, including:
- Spyware: Programs that secretly collect user information.
- Ransomware: Holds your data hostage until a ransom is paid.
Understanding these threats can better prepare you for recognizing and combating them effectively.
Signs of a Virus Infection
Before you can remove a virus from your laptop, you need to recognize the signs of infection. Common indicators include:
- Slow performance: Your laptop takes longer to boot up or run applications.
