As is the case with virtually any software option, antivirus courses use laptop resources – they start files, examine information in them, unpack records for encoding etc . A lot more thorough the data scanning is definitely, the more learning resource consumption will probably be. Therefore , you need to balance course velocity and the a higher level security offered – a great iron door protects more effectively than a slim one although requires more effort to open and close.
For many people, it may seem that all antivirus alternatives are the same – the products of various companies vary only simply by design and marketing. Indeed, it is true the market for standard anti-virus solutions is extremely consolidated, with Symantec, McAfee and NAI (Trend Micro) taking over the market in terms of earnings.
But it is likewise the case that, despite this, there are still a lot of problems with antivirus security. The main one is that, as already stated above, antivirus protection relies on the fact that viruses honor a set of clear rules. However , these rules are not fixed, but rather frequently check this transform according to the desired goals of the villain computer underground. As a result, not necessarily possible to build a general virus scanner that can always detect almost all viruses and Trojans.
