Antivirus software usually works on one of two principles: Either it scans programs and files as they enter your device and compares them to known viruses, or it scans programs already on your device, looking for any suspicious behavior. Strong antivirus software, such as the ones we list below, do both. In addition, most antiviruses feature tools to either remove or quarantine offending malware.

The Features Of Antivirus Software :
1) Easy To Manage
The solution must be usable—both for the end-user and for admins. Admins often have several programs they need to manage, so they don’t have a huge amount of time to spend getting to grips with new solutions.
2) Recognize Polymorphous Attacks
Polymorphic malware is a form of malware capable of evolving and altering its properties to avoid detection.
3) Automatic Updates
For all forms of software, updates are a necessity.
4) Real-Time Scanning
This is an incredibly important feature in any antivirus product.
5) Backups
This is a feature that a lot of antivirus solutions offer, but not all of them.
