At first glance, choosing an antivirus is a simple idea. By purchasing a well-known and well-proven antivirus, the user has the right to expect that all system and personal files will be safe. Each time, only one point is not taken into account - this is the power of the computer itself. In order not to reduce PC performance, it is advisable to select an antivirus program taking into account several factors.
It is impossible to tell which antivirus is the best in the world. Having asked this question, on the Internet, you can easily find lists already compiled by someone. You can talk about the incorrectness of the task by opening only a few sites with this topic. The rating of antivirus software varies from portal to portal.
It cannot be said in advance that a particular antivirus is better than another, because the same antivirus program cannot work the same on all computers. A program that works well for your friend can cause problems and freezes on your computer.
The use of RAM by antivirus is rarely taken into account by users, which creates certain problems associated with a decrease in performance.
To solve its daily tasks, anti-virus software uses computer resources, including RAM. A sharp decrease in performance during scanning can be detected by users whose system units and laptops are equipped with two or less GB of RAM. To prevent this from happening, you can read the system requirements on the boxes with the software product. Based on practice, anti-virus solutions, which have a large set of functions and utilities in their arsenal, load the computer the most.
Most of the unnecessary functions of the antivirus can be easily disabled in the settings and run only when necessary.
When choosing an antivirus product, you need to consider not only its cost, but also the ability to contact support if your computer is infected with a licensed antivirus on board. At the time of this writing, only Dr. Web and Kaspersky provides such a service. Computer security specialists of these companies will help decrypt files corrupted by a ransomware virus.
