An antivirus is a computer protection tool designed to eliminate potential threats such as computer viruses, malware and malicious encrypting tools. Some malware may inject deep inside the system and modify its so that your computer’s normal functionality is affected.
Computer scanning is a powerful method of identifying malicious and potentially unwanted programs that may interfere with the normal functionality of the computer.
How malicious files are detected by the antivirus?
Simple signature search aside, modern antiviruses rely on heuristics to discover programs that may integrate potentially dangerous code. Because of heuristics, the antivirus may designate as malware just about any program that includes functions with unusual (and potentially dangerous) system calls.
This way the antivirus differentiates a malicious file from a general document that has nothing to do with the computer’s normal operation. Due to this reason, sometimes a harmless file may be recognized as a malicious one even if it does not pose a real threat.

Along with PC scanning, one of the most important settings is Quarantine. This is critically important, and this is the only place where an antivirus program can relocate the “neutralized” files to. Usually, quarantined files are not subject to immediate deletion unless Avast discovers a specific threat for the system. These files are deposited into a specialized storage for further assessment by the device administrator.
