Automatic updatesДЄny antivirus software worth its salt will automatically update itself, both to clean up any vulnerabilities it might have and to keep its virus database and capabilities up to date. The industry calls this a вЂњ false positiveвЂќ and it is a criterion used to judge the quality of an antivirus.

Then there is the full system scan, where the antivirus goes through every nook and cranny of your device in order to find malware or any other suspicious software or files.

ItвЂ™s all done in the background, and the scanned file or program only opens once the antivirus has finished the scan. Basically, it scans any new program or file before itвЂ™s opened and checks if it is a known malware or if it behaves like one. Reactive scanningВ is the bread and butter of an antivirus.
