  It goes without saying that in our computerized age, protecting information or entire systems from exposure is extremely necessary. In other words, any computer, in addition to the built-in tools of the system itself, must have at least some more or less functional antivirus. Let's try to look at the lightest antiviruses and, based on the test results, determine what is best suited to provide protection today.

  Safety comes first!

  As for antivirus software, now you can find not tens, but hundreds of options. Of course, it will not be possible to consider all of them, especially since in terms of functionality they are completely unequal to each other.

  Therefore, we will focus on several of the most famous software products. Perhaps comparative results will tell someone which is the best lightweight antivirus for XP or server version of Windows. Let’s immediately make a reservation that the same “expert” system, although it still remains a very popular and in-demand system, is nevertheless hopelessly outdated. However, a solution will be proposed for this too.

  The lightest antiviruses: main aspects of testing

  Of course, not every person who constantly works with a computer can afford to purchase the most modern configuration with a powerful multi-core processor chip, large RAM, a modern video card, etc. Therefore, let's see what tests show for the lightest antivirus for a computer with an average configuration. Let's take as a basis Pentium processor 4, 1 GB of RAM and an 80 GB hard drive. I think this will be just right for testing.

  As for the main tests, let's look at the performance of several independent laboratories. Among the checks we highlight the following:

  • parallel work with resource-intensive applications;
  • threats from unsafe sites;
  • speed of copying or moving data on the hard drive;
  • work in the background.

  Kaspersky Internet Security

  So, before us is one of the most famous anti-virus packages of our time. Many may object. Why was it necessary to include a Kaspersky Lab software product on the list? The fact is that, unlike all other antivirus packages, this program is the least demanding of system resources.

  

  The test results on the above configuration, although not ideal, look quite encouraging. This primarily concerns the definition potential threats when browsing the Internet or installing any software. However, along with this there are also obvious disadvantages. So, for example, the loading time of the system itself increases significantly; after it starts, it takes a long time to connect via a Wi-Fi connection; when downloading files using the same torrent client, the saving time to disk is quite long. This is due to checking content in real time. By the way, Kaspersky is the only package for which this time is off the charts.

  When contacting hard drive(copying files) there is a clear slowdown in work. Not critical, but still there. And when you launch the Photoshop package, the system starts to slow down in earnest (the antivirus itself consumes too much RAM). So it’s hard to say that this is the easiest antivirus for a laptop or desktop terminal. In principle, it can be used if you do not work with heavy applications in parallel. But in terms of protection, it is among the leaders, even despite the increased load on system resources.

  ESET Smart Security

  Another major player in the antivirus software market is the package Smart Security from ESET. On at the moment The eighth version of the program is available.

  

  In principle, the behavior of this application is somewhat reminiscent of Kaspersky. The system boot time is increased, in addition, the initial check of automatically loaded components takes quite a long time (this is especially noticeable in Windows XP). The defense as a whole showed good results even with the Anti-Theft function turned off. There are no delays when accessing the hard drive, and there are no problems with the speed of access to the Internet, however, when launching Skype The application takes quite a long time to load. However, if you look at the monitor of used resources, you will notice that the load is not as great as it might seem at first. Maximum Peaks it reaches only during the updating of the anti-virus databases and the initial scan. You can and should use it, too, but you can’t call it the fastest, although compared to Kaspersky it’s heaven and earth.

  Dr. Web Security Space

  Now about another well-known package, which is rightfully considered one of the best means protection of computer systems.

  

  What do its results show? Firstly, during installation the program prompts you to install your own firewall, which you should not do under any circumstances, since conflicts with the native Windows firewall may arise and a significant increase in the load on the system. The system loads quite quickly (according to the report, approximately 60-65 seconds), but in reality it takes much longer for access to the hard drive to stop completely. In parallel with Photoshop work almost impossible Wi-Fi network When connected, it thinks a little longer than usual, but in everything else the performance is quite high.

  Now the fly in the ointment. As it turned out, the program sometimes spontaneously activates something like a hidden full check. At the same time, the load on CPU can increase by 50%. However, this is only observed when using standard settings default. If you disable everything unnecessary, you can get high-quality protection.

  Avira Antivirus Pro

  Avira makes a pretty good impression. In principle, in terms of its performance, the antivirus is somewhere in the middle of the list. Its only problem is running resource-intensive applications. With Photoshop this is not too pronounced, but some refuse to work with guest (child) operating systems (at least when they are launched for the first time).

  

  In general, it cannot be said that this is the lightest; nevertheless, it can be used as reliable protection (especially since it is unlikely that anyone will install virtual machine). To describe it briefly, it’s a good, solid average.

  Avast Internet Security

  Regarding this software product, in almost all indicators it scored true, some errors were noticed when identifying potential threats.

  

  But when launching Photoshop or accessing the hard drive, monitoring the load on the system showed unprecedented results. For example, RAM consumption in active mode is only 80-100 MB! The only negative is the excessive talkativeness of the program. Yes, yes! It is talkativeness, since it is enabled by default voice mode alerts. However, it won't be difficult to turn it off.

  Microsoft Security Essentials

  Finally, the native brainchild of Microsoft Corporation. As testing shows, he is also in mandatory should be included in the "Lightest Antivirus" list. Since Windows systems are the most common in our country, it fits them almost perfectly, because who, if not the creators of this family of operating systems themselves, knows what kind of holes in the security system they have. In addition, when using this package, conflicts in the firewall are eliminated.

  

  For all other indicators, the result can be called satisfactory, except for the excessive load on the system when accessing the hard drive. Sometimes during installation third party programs False positives may occur because some of them try to make the necessary changes to system files.

  Which antivirus is the lightest?

  What do the results of the test, in which the lightest antiviruses were presented, say? Avast demonstrates the best overall performance. First of all, there is virtually no load on the system, even when working with heavy programs. The protection system, of course, is not ideal, but for weak machines or configurations based on Windows XP, I think it is ideal. Moreover, if we do not take into account technical aspects, we can say that Avast is the most easy free antivirus. But most programs must either be purchased or constantly activated when using even shareware versions.

  On the other hand, today there is not a single program that would meet high security requirements, and at the same time not load the system. And, of course, other well-known antiviruses like Bitdefender and those based on it were not considered here, due to the fact that the antivirus itself is too power-hungry, and its modifications like 360 ​​Security, although they work quite quickly, do not provide the proper level of protection, and even often give false alarms. However, what exactly to use is a purely personal matter.

  PCMag portal tested all popular solutions in the category free antiviruses during 2016. This rating allows you to choose the best free antivirus for Windows protection computer

  Antivirus vendors typically pay for the opportunity to participate in testing because lab reports help improve products. The number of laboratories that include a particular product primarily indicates its importance. In any case, to test an antivirus, two conditions must be met: the laboratory must consider the product important enough, and the development company must be satisfied with the cost of participation. Laboratories are not required to conduct tests free products, but many vendors include full protection in free solutions, adding to paid products advanced features.

  PCMag's own amateur tests

  In addition to its rigorous analysis of lab test results, PCMag performs its own amateur program-blocking testing of antivirus products. Every antivirus encounters a set of malware different types, after which the product’s reaction to the threat is recorded. Typically, an antivirus removes most samples at once and detects several more instances of malware when it tries to launch. Based on the test results, the product can receive from 0 to 10 points for blocking, depending on how thoroughly it protects the system from test threats.

  The test collection has been in use for months, so the malware blocking test does not provide any indication of an antivirus's ability to detect the latest threats. A separate test attempts to load malware from online sources no more than a day old, provided by the MRG-Effitas laboratory. The testing process notes whether the product blocked access to a network location, cleared the malware payload during download, or ignored the threat. Avira Free Antivirus received the highest score in this test, followed by McAfee and Symantec in the final table.

  Useful features

  Each antivirus product in the collection scans files on access to prevent potential malware from running, and also scans the system on demand or on a set schedule. Blocking access to malicious links - great way avoid trouble. Many products extend protection to prevent you from visiting fraudulent or phishing sites that try to steal your credentials. Some solutions assign ratings to results search results, flagging suspicious and dangerous links.

  Behavioral detection is featured in some products in the collection. On the one hand, this component can detect malware, which are unknown threats. On the other hand, behavioral analysis can lead to false positives for reliable programs.

  One in a simple way For maximum protection computer is to install security updates for Windows OS, browsers and other popular programs. Windows 10 made updates mandatory for consumers, but remains large number gaps in popular applications and plugins. Vulnerability scanning in the form of missed updates is a feature often found in commercial antivirus products. However, some free antiviruses have similar functionality.

  Who was not included in the rating

  This article contains information only about free antivirus solutions, which received at least a “good” rating from PCMag reviews. Among those products that were not included in this rating- Windows Defender, which was given 2.5 stars. Microsoft participates in tests of all monitored antivirus laboratories, but only as basic protection. If a product cannot exceed the basic level of protection, it is not worth considering.
