What does an antivirus software do

An antivirus is an anti-malware software program that helps computer users to protect their devices against infected programs, trojan horses, worms and other malicious software. A comprehensive antivirus suite not only keeps your PC safe from malware but also improves performance, and can keep your other subscriptions running smoothly.

You wouldn’t worry too much about protecting your home from break-ins if you lived in the most affluent area of town. Similar logic applies to computer security. The likelihood of hackers targeting your website is directly related to how many other websites are competing for their attention. If your business falls into one of these hacker-targeted industries, having effective security measures in place is even more important.

Antivirus software is designed to protect your computer from viruses, spyware, and other malicious code that can cause damage to your system. It does this by scanning your computer’s files and looking for any suspicious activity. If the antivirus software finds anything suspicious, it will alert you so that you can take action.

Antivirus software is software that protects your computer from viruses and other malicious programs. It does this by scanning your files and looking for any signs of threats, then either removing or quarantining them.

The best antivirus software can detect new threats before they even have a chance to do damage to your system.

What Does Antivirus Software Do in Your Computer

An antivirus software, or shortened to AV software, is a software program designed to identify, remove, or isolate malicious programs and codes that may get installed or infect your system. Viruses are computer codes that have the ability to replicate themselves and attach themselves to the operating system’s main code in order to be executed.

Once established, they perform their functions which include but not limited to encrypting important data, leaking out information, destroying the operating system, or even worse, locking out the user from accessing their device. Spyware and other malware do similar things but mostly tracking your actions and collecting your personal information.

Antivirus software therefore performs three major functions.

  • Identifying malicious codes in the system.
  • Removing them by destroying or isolating them.
  • Most importantly, protecting your device from getting infected with such malicious codes.

Keep in mind that not all antivirus software can detect all types of malicious codes in your system and it is therefore important to ensure that you have only the best AV software installed to safeguard you from cyber-attacks.

How Does Antivirus Remove Viruses

The antivirus is designed to identify malicious codes, Trojan horses, spyware and other malware programs that corrupt the system and cause malfunctions. The Trojan horses, for instance, have the ability to disguise themselves as legitimate programs enticing the user to install them. The AV software should be able to detect this and alert the user before installing such programs.

It does this through three different ways.

  • Specific detection – This is whereby the antivirus scans the device for suspected malware programs using a set of predefined characteristics of code base. It does this by comparing such suspected codes to those predefined characteristics and alienating those that match up.
  • Generic detection – Sometimes not all predefined characteristics do not define all types of virus codes. The AV software then uses its knowledge of malware codes to identify pieces of codes that might appear malicious and alienates them. The user is then allowed to determine whether they think it’s a safe program and if they’re unsure, the program is removed from the system.
  • Heuristic detection – This final one is the most complex of all as the malware or virus infecting the system is not known by the AV software. So the antivirus scans through the system looking for actions that raise red flags or appear abnormal. Once identified, the program is flagged and removed or alienated from the system.
