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.
Features of antivirus :
1. Real-time Scanning
While all antivirus software is specifically designed to detect the presence of malware, not all of them detect in the same way.
2. Automatic Updates
Updates are vital for all forms of software, but this is especially true when it comes to antivirus.
3. Protection for Multiple Apps
Threats exist across the entire spectrum of apps and services that you rely on for your everyday tasks.
4.
Auto-Clean
If the antivirus software immediately detects malicious software, why wouldn’t it delete the code on the spot? Unfortunately, some solutions simply place the malware in a quarantine zone upon detection, waiting for the user to log on and manually delete it.
5.
Fights Against All Types of Malware
Between trojans, bots, spyware, viruses, etc., there are many different types of malware that can harm your computer, and antivirus programs are sometimes designed only to target a specific type of software. It’s better to go with a program that can comprehensively detect all or almost all of the various forms that malware takes.
