As is the situation with virtually any software choice, antivirus programs use pc resources — they wide open files, go through information in them, unpack records for scanning service etc . The more thorough the details scanning is normally, the more useful resource consumption will be. Therefore , you need to balance course rate and the amount of security given – an iron door protects more effectively than a skinny one but requires even more effort to open and close.

Without a doubt, it is true the fact that market with regards to standard antivirus solutions is very consolidated, with Symantec, McAfee and NAI (Trend Micro) taking over the sector in terms of revenue.
But it is also the case that, despite this, there are still a lot of problems with antivirus security. The main one is the fact, as mentioned previously above, antivirus protection relies on the fact that viruses follow a set of well-defined rules. However , these rules are not set, but rather regularly see this website modification according to the desired goals of the unlawful computer underground. As a result, it is far from possible to build a general virus scanner that can always detect pretty much all viruses and Trojans.
