Answering this question is not easy. Because what works today may not work tomorrow. But there are certain security features which should be a part of every antivirus software. In other words, these are security features which lay a solid foundation for resisting malware and which form the crux of every Good Antivirus Software. Therefore the answer to the question, 'what's the best antivirus software', can be decided based on whether the antivirus software includes the following technologies or not. The best antivirus is the one which:

• Checks Everything Before Letting Them Into Your PC: Almost any application – be it a free download or a web service – can pose a security threat today. Therefore your antivirus software should check everything and anything before granting them access to your computer. This is usually done via blacklisting (not allowed by default because they've proven to be harmful), whitelisting (allowed by default because they've proven to be harmless) and testing unknown applications separately (because they are yet to be tested).

• Contains Solid Malware Surveillance or Monitoring System: What if your PC is already infected? Even before you install antivirus? Therefore it only makes sense to expect your antivirus to contain a solid malware surveillance system which monitors your PC(s) through comprehensive scans. This is not only useful in case your PC is already infected but otherwise as well, as the chances of the modern-day malware defeating the most secure security systems are pretty high. If such a situation arises, having antivirus equipped with malware surveillance system can minimize the damage greatly.

• Regulates Internet Traffic Efficiently: Another important security feature your antivirus should include. After all, effective PC protection cannot be implemented without regulating the internet traffic. Because the internet is the breeding ground for malware. Therefore your antivirus should have the mechanism to regulate the internet traffic. In other words, it should come equipped with a firewall.

• Offers Safe/Secure Browsing Environments: To protect sensitive online transactions, antivirus software usually include or offer safe/secure browsing environments which are definitely more impervious to malware attacks and security threats than your normal browser. Therefore look out for this security provision while selecting antivirus.

• Runs Antivirus Scans Even Before Your PC Boots Up: Some malware has the capacity to infect your PC(s) even before it's OS loads. These are probably one of the most dangerous types of malware, as recovering from these infections is almost impossible – unless your PC is equipped with an antivirus software which contains pre-boot scanning capabilities. Another feature you should look out for.

• Offers Malware Removal Support: Finally, provision for malware removal – either through human analysis or other alternative options. You may question why do I need this while I have antivirus for protection. While this is a valid question, the fact that the cybersecurity threat landscape is changing rapidly and the chances of a malware escaping the securest of secure systems is higher than. Therefore PC users like you have to be prepared for the worst.
