As is the truth with any kind of software option, antivirus applications use computer resources – they start files, reading information in them, unpack archives for scanning service etc . The greater thorough your data scanning is usually, the more useful resource consumption will probably be. Therefore , it is necessary to balance application swiftness and the standard of security presented – a great iron door protects more effectively than a thin one but requires even more effort to open and close.

For many people, it could seem that every antivirus solutions are the same — the products of numerous companies are different only by design and marketing. Indeed, it is true which the market designed for standard ant-virus solutions is incredibly consolidated, with right here Symantec, McAfee and NAI (Trend Micro) taking over the sector in terms of earnings.

But it is usually the case that, despite all this, there are still a lot of problems with antivirus protection. The main one is that, as mentioned previously above, antivirus protection relies on the fact that viruses honor a set of clear rules. However , these guidelines are not fixed, but rather constantly improve according to the desired goals of the lawbreaker computer subterranean. As a result, it is not necessarily possible to develop a common virus reader that can generally detect almost all viruses and Trojans.
