Detailed explanation-1: -Antivirus products work by detecting, quarantining and/or deleting malicious code, to prevent malware from causing damage to your device. Modern antivirus products update themselves automatically, to provide protection against the latest viruses and other types of malware.
Detailed explanation-2: -On average, antivirus software is only 25% successful at detecting malware. Statistics on computer viruses and antivirus software show that, unfortunately, the malicious apps are winning the battle. Currently, “popular” malicious programs are having a field day, even against top-of-the-line antivirus software.
