Antivirus software is a type of program that is designed to prevent, detect, and remove malware infections on a computer. It works by scanning the computer’s files and system for known malware signatures and also by using heuristic algorithms to identify suspicious behaviour that may indicate the presence of malware. When a threat is detected, the antivirus software will either remove the malware immediately or quarantine it so that it cannot cause any damage.

Antivirus software is essential for protecting a computer from malware infections, which can cause a wide range of problems. Malware can steal sensitive information, corrupt files, and even render a computer unusable. Antivirus software can help to prevent these problems by providing a first line of defence against malware attacks.

There are many different antivirus programs available, and they come in a range of prices and features. Some are free, while others are paid and offer more advanced features. It’s important to choose an antivirus program that is reliable and has a good reputation.

One thing to keep in mind is that no antivirus program is 100% effective. There are always new types of malwares being created, and it’s impossible for an antivirus program to be able to detect and protect against every single one. However, using antivirus software can significantly reduce the risk of a malware infection and provide peace of mind.

In addition to using antivirus software, there are other steps that you can take to protect your computer from malware. These include:

• Keeping your operating system and other software up to date with the latest security patches.
• Avoiding suspicious websites and email attachments.
• Using a firewall to block incoming connections from potentially malicious sources.
• Regularly backing up your important files to prevent data loss in the event of an infection.

Overall, antivirus software is an important tool for protecting your computer against malware infections. While it is not a complete solution, it is a crucial part of a comprehensive security plan.
