As is the situation with virtually any software remedy, antivirus programs use computer system resources – they open up files, go through information in them, unpack records for deciphering etc . A lot more thorough the information scanning can be, the more learning resource consumption will probably be. Therefore , it is necessary to balance course buyers evaluate risks velocity and the standard of security supplied – a great iron door protects more effectively than a slim one nonetheless requires even more effort to spread out and close.
For many people, it may seem that all antivirus alternatives are the same – the products of various companies are different only by design and marketing. Without a doubt, it is true the market designed for standard anti virus solutions is incredibly consolidated, with Symantec, McAfee and NAI (Trend Micro) ruling the sector in terms of earnings.
But it is additionally the case that, despite this all, there are still some problems with antivirus security. The main one is the fact, as already mentioned above, antivirus security relies on the fact that viruses respect a set of clear rules. However , these rules are not set, but rather regularly change according to the goals of the lawbreaker computer underground. As a result, it is not necessarily possible to build a widespread virus scanner that can usually detect pretty much all viruses and Trojans.
