Light antivirus
When choosing one or another antivirus program, today more and more users are making a request for the so-called «light antivirus» What is the special feature of such a program? As the experts promoting this type of program say, their «lightness» lies in the fact that such an antivirus is able to perform its protective functions «from the cloud». Working in real time, light antivirusslightly slows down the overall speed of the system. Compared to other antiviruses, when installing and using «air» ones, the speed of the system increases by 50%. This type of antivirus program is optimal for installation on a PC with a low performance indicator. The ability to ensure the lightness of the antivirus without reducing its efficiency is achieved by the fact that all antivirus actions are carried out at the expense of the resources of the manufacturer's company, not the computer.
Free antivirus testing
Now let's look at some of the methods by which both a free antivirus test is carried out, as well as paid programs. Based on its results, you can identify the most effective antivirus or simply the most optimal one for you. The essence of the testing process is to launch a scan of the security program on demand of the catalog with a list of virus programs. For testing free antiviruses, the most «complex malware» are selected for the catalog to create a situation similar to reality. The catalog for testing includes both new and the earliest virus programs found on the Internet. During testing, no additional actions were performed with the security program, except for installing the antivirus. The databases of the tested antiviruses are updated simultaneously. During the evaluation, such parameters as the number of detected viruses, the time spent on identifying viruses, and the amount of space occupied on the computer were taken into account. Based on the testing results, the «winners of the competition» are identified. Today, the following are recognized as such: Kaspersky, Dr.Web, NOD32, Outpost, Panda, AntiVir, Avast.
