As is the truth with any software option, antivirus programs use pc resources – they wide open files, read information in them, unpack archives for deciphering etc . The more thorough the data scanning is definitely, the more powerful resource consumption will probably be. Therefore , it is necessary to balance method rate and the volume of security offered – an iron door protects more effectively than a slim one yet requires even more effort to spread out and close.

The main one is that, as already mentioned above, antivirus protection relies on the fact that viruses honor a set of well-defined rules.

As a result, it is far from possible to make a common virus reader that can usually detect pretty much all viruses and Trojans.
