Allgemeines Schema der Antiviren-Arbeit

Im Wesentlichen können Antivirenscanner in zwei Modi arbeiten. First is a real-time scan when the antivirus program runs in the background and constantly checks on potential threats. If it comes across something presenting danger, it will notify you. Das Programm stoppt bösartige Aktivitäten der Bedrohung, bevor sie Ihrem Computer und Ihren Dateien Schaden zufügen können.

The second work mode presents itself as the scan of an entire system. This is a one-time action that takes a significant amount of time. You should not do this kind of scan too much, especially if you have your antivirus run in the background. But it would be useful to run a full scan of a system once in some weeks to double-check everything. In the meantime, your constantly running background antivirus scan should stop any potential danger if there occurs.
