How does antivirus software work and protect our PC?

The role of an antivirus on a Windows PC has always been a bit confusing for the users. Some believe that they are crucial as an antivirus protects your PC from unnecessary viruses, malware, and malicious software/files. On the other hand, there are several beliefs that such programs are of no use and are just a facade.

If you have doubts and want to know how an antivirus protects your PC, then this post is for you! Keep on reading as by the end of this one, you will be able to identify every aspect of an antivirus. We will also share the best antivirus you can opt for so stay tuned for that!

What is an Antivirus? Overview

Antivirus software, as we all know, helps keep data safe from cybercriminals. They have been around nearly as long as viruses that call for their use. This software checks the web pages, files, folders, software, applications, connected devices, and each part of the system for infections. When a threat is detected, the antivirus or security tool running on the system blocks and removes it from the system. 

This gives the user peace of mind, as the computer virus designed to damage and infiltrate the operating system is taken care of by the antivirus you are using.

How Does Antivirus Work?

You might have a basic idea of what an antivirus does. It scans your files and compares the integrity of files with the database to determine whether they are safe or not.

Viruses are no different than a normal software program. They operate similarly; however, their intent is not genuine.

Computer viruses are designed to harm your system and steal data. They contain a signature (fingerprint) that sets them apart from other genuine programs running on the system, making them unique and recognizable as a threat by the antivirus software.

Antivirus software to identify a file as genuine or infected scans the signature of each file. When a malicious pattern stored in the database is detected, the file is flagged as malicious. This is one way of detecting malicious files. But what about the latest viruses, details of which have not yet been added to the database?

Antivirus programs use heuristic detection to overcome this problem. This means instead of depending on one signature, they combine related ones and detect threats. Alongside, antivirus software also uses sandboxing. This means the antivirus software will run the file or software considered malicious and observe its behavior. It is classified as an infected file if anything different from normal is detected.

Types of Infectious Files that Antivirus Software Can Protect Us From

If we go into further detail about viruses and their types, we can find that there are different types of files, used with different intentions to cause different issues on a PC. While your internal security measures may help you stay safe from basic viruses, you need to have a professional antivirus program to stay protected from all types of files.

  • Spyware – information-stealing threats.
  • Computer Viruses – unwanted programs that enter the system without the user’s knowledge replicate themselves thus affecting the system’s performance and user data.
  • Worms – are malware replicating itself without human interaction and causing damage without attaching themselves to a software program.
  • Adware – advertising-supported software- is distributed within the software or forces users to install additional software to earn money.
  • Phishing Attacks – a social engineering attack that steals user data, including credit card numbers and login credentials.
  • Malware – short for malicious software is an umbrella term for viruses, worms, trojans, and other nasty threats that harm the system and its functioning.
  • Trojans – a type of malware that disguises as legitimate software.

Besides, there are other types of threats like keyloggers, smishing, etc., from which an antivirus protects us.

Signs your System is infected

Though antivirus software requires no special reason to exist on a PC and must be installed by default, there are a few signs that can give you a better idea that the system requires it. Whenever an infected file makes its way to your computer, certain issues pop out on the PC. These issues are the signs that your PC has been infected and an antivirus program is required.

Some such signs are – 

  • Slow system performance
  • Frequent crashes
  • Unnecessary Pop-up Ads
  • Data loss
  • Unable to connect to the internet or open files

If any of these issues exist on your computer, you have no other option but to use antivirus software as that is the easiest and your best option to resolve them.
