Before we tell you how to recover these files, let us find out what is an antivirus, how it works and why it can suddenly block any file without obvious reasons.

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.
