Antivirus software is a program designed to protect your computer from malware, a term that refers to any software that is harmful to your computer. This includes viruses, worms, Trojan horses, and other malicious software. Antivirus Protection runs on your computer and scans your files and programs for any signs of malware. If it detects any malware, it will remove or quarantine it to prevent it from causing harm to your computer.
This article will discuss why you need antivirus software and the importance of protecting your computer.
Types of Malware
A computer virus is malware that attaches itself to a program or file and then replicates itself. It can cause a wide range of damage to your computer, from deleting files to stealing personal information.
A worm is a type of malware similar to a virus, but it can replicate itself and spread to other computers without human interaction. It can cause damage by consuming resources on your computer, such as memory and bandwidth.
- Trojan horses
Malware that poses as a trustworthy program is known as a Trojan horse. The Trojan horse will infect your computer when you run it, giving hackers access to your data.
Ransomware is malware that encrypts your files and requests payment in exchange for their decryption. It can cause severe damage if you cannot access your important files and documents.
- Adware and spyware
Adware and spyware are types of malware that can track your online activities and display unwanted ads. They can also steal personal information, such as login credentials and credit card numbers.
Harmful Effects of Malware

How antivirus software works
With so many top antivirus protection options available, it can take time to know where to start.
- Signature-based detection
Signature-based detection identifies malware by matching it to a known pattern or “signature” in its code.
Antivirus software uses a database of known malware signatures to scan your computer for matches. When it finds a match, it can identify the malware and take action to remove it.
- Behavior-based detection
Behavior-based detection is a method of identifying malware by analyzing its behavior on your computer.
Antivirus software monitors your computer for suspicious activity and can identify malware based on its behavior. For example, if a program tries to access sensitive data, the antivirus software may flag it as malware.
- Heuristics-based detection
Heuristics-based detection is a method of identifying malware by analyzing its code and behavior to find patterns that indicate it is malicious.
Antivirus software uses heuristics to identify patterns indicative of malware, even if it has not been seen before. This can help to detect new and unknown malware.
- Cloud-based detection
Cloud-based detection identifies malware by analyzing it in a cloud-based environment rather than on your local computer.
Antivirus software sends a copy of a suspect file or program to a cloud-based service for analysis. The service can then determine if it is malware and take action to remove it.
- Real-time protection
Real-time antivirus protection is a feature that continuously monitors your computer for malware in real time.
Antivirus software uses a combination of the above methods to scan your computer for malware in real time and can take action to remove it when it is detected.
These other methods work together to provide comprehensive security for your computer.
