As is the case with any software answer, antivirus programs use computer resources – they wide open files, read information in them, unpack archives for scanning etc . The greater thorough the data scanning is normally, the more source consumption will probably be. Therefore , it is necessary to balance program rate and the amount of security supplied – a great iron door protects more effectively than a slim one but requires even more effort to spread out and close.
For many people, it might seem that most antivirus solutions are the same – the products of varied companies fluctuate only by simply design and marketing. Certainly, it is true the fact that the market for the purpose of standard anti virus solutions is extremely consolidated, with Symantec, McAfee and NAI (Trend Micro) dominating the market in terms of income.
But it is also the case that, despite this, there are still a few problems with antivirus protection. The main one is that, as already mentioned above, antivirus security relies https://pceasyblog.org/top-free-vpn-for-windows on the fact that viruses accept a set of well-defined rules. Nevertheless , these rules are not fixed, but rather frequently switch according to the desired goals of the prison computer underground. As a result, it isn’t possible to develop a general virus scanning device that can at all times detect all of the viruses and Trojans.
