What Is Antivirus Software?

An ideal Antivirus software is the one that provides users with top-notch protection against multiple kinds of threats, including viruses, malware, spyware, adware, trojan horse, rootkits, worms, ransomware, and other malicious content. If you don’t run a good antivirus software on your devices, there are high chances that you might encounter the following issues on your device:

How Does Antivirus Software Work?

Usually, Antivirus program works on either of the principles: 

  • Comprehensively scans programs & files as soon as they enter your device and compares them with potential viruses. 
  • Scans your entire device for existing programs and files to detect any suspicious behaviour. 
  • Additionally, ideal antivirus software promotes features that can help users to completely eliminate or quarantine the harmful traces. 

In both scenarios, the security software uses a conventional method that looks for signatures to detect new malware. It matches the detected threats with their in-built extensive database of already known viruses and malware that teaches the utility about how to detect, flag and eliminate malicious content. Apart from this, antivirus programs can use the following virus detection methods that help users to protect their device. These include: 

  • Heuristic-based detection: In this form of detection, the utility uses an algorithm to compare the signature of viruses against a potential threat. Antivirus software that uses this type of detection method, can certainly identify viruses that have not been discovered yet. Hence, the perk is that it can easily find new viruses but the downside is, it can also generate false positive results. Means, it may indicate an uninfected file or program as infected one. 
  • Behaviour-based detection: This form of detection works very well, when it comes to detecting the type of malware that attempts to steal your personal information. Antiviruses equipped with this type of method strictly observes the behaviour of programs and files stored on your computer and if found problems, shows the warning like below: 
  • Settings of the programs are changed. 
  • Some files are modified or deleted. 
  • Remote connection is established. 
  • Sandbox Detection: In this form of virus detection method, the antivirus software runs all the programs in a dedicated virtual environment and closely monitors and records its action to further identify whether those programs are malicious or not. Once it observes that the program is safe to run, it executes it in the real environment. 
  • Data Mining Detection: Well, this virus detection method is advanced enough to detect the latest trends in malware and other threats.  

Besides these virus detection methods, the Antivirus Software offers multiple kinds of scanning methods to safeguard your device. This includes: 

  • On-Demand Scan 
  • Real-Time Protection
  • Other Advanced Scans 

Some of the protection utilities will ask for your permission before removing the suspicious files. While, some provide a hands-on approach to alter the settings, so that antivirus tools can automate the entire process of eliminating harmful files.
