Many manufacturers of protective equipment are produced free edited by antiviruses that can be completely free to download from the manufacturer's official website and use on their computers.

Most developers include only anti-virus scanners without constant protection, but there are developers who provide a full range of tools to protect your data in their free version.

Below is a selection of antiviruses that you can download and use absolutely free.

Safety does not happen little. So consider many manufacturers of protection systems. Including the developers of free antivirus 360 Total Security, which includes as many as 5 engines. Yes, this antivirus has many different engines, each of which performs its task.

So I got hands to free Comodo Internet Security. This is a set of tools for protecting your computer, which includes firewall, antivirus and proactive protection module. I will not describe all the properties of Comodo Internet Security, because they, in my opinion, are standard and are present in most similar programs. The main difference between this program from the rest in its free and amazing reliability. With proper configuration, the program allows you to secure the computer to the maximum. The other day I revised several comparative tests that were conducted by various companies, and the results of these tests were quite surprised. As an example, I will give the results of one of these tests.

Today I will tell you about the next free Antivirus Avira Free Antivirus, who the other day settled on one of my computers. The situation with it is special, since this antivirus is not a simple scanner, it is not necessary to download it every time you need to check the system. This antivirus hangs in memory and does everything alone. Self downloads and installs updates, independently checks the files to which the operating system and various applications are drawn.

Wannacryptor, Wannacryptor, Mass Attack, has led tens of thousands of computers in organizations and public institutions around the world. The malware uses the well-known vulnerability described in the MS17-010 security bulletin and the EternalBlue / DoublePulsar exploit combination, which allow you to attack other vulnerable Windows systems in the same network. As a result, the infection of one computer can lead to compromising the entire corporate network in the organization.

After appearing on the computer by successful vulnerability operation, Wannacry encrypter encrypts all files and documents of specific formats, performing remote commands sent via the SMB protocol and extending to other Windows computers on the network.

You may be too trusting, and therefore did not install the antivirus to your PC, or the license to your antivirus has already ended, or the antivirus installed you do not provide maximum protection, and ... maybe your PC is infected!

Dr.Web Cureit! - Antivirus, which is noticeably different from all programs familiar. This utility does not work constantly, preventing the emergence of a malicious software on the computer. It allows you to cure already infected PC from viruses, Trojan horses, rootkits, etc. This feature Dr.Web Cureit! Determines the scope of application of this product. It can be used periodically to test the reliability of the antivirus installed on the computer, as well as in cases where the infection of PC can be suspected of indirect features. In general, the favor of Dr.Web Cureit! It is difficult to overestimate.

Continuing the popular theme about the free antivirus, I want to mention another development with which I met relatively recently and who has not yet had time to write. In theory, it would be possible to add this information to the original post, but I decided to arrange everything in the form of a separate note. So, today we will discuss the free antivirus from Kaspersky Lab called Kaspersky Virus Removal Tool.

Today, do not use the antivirus when working on the Internet - akin to suicide. Nevertheless, there are personalities who neglect these golden rules and catch the clouds of different infection on their laptop. Save the situation very often allows antivirus check without installing it in the Windows operating system. Moreover, after infection, very often malicious software does not give anything more. Today I will tell you about several antivirus scanners working in Portable mode. Such a utility can be downloaded for a USB flash drive and run on an infected system. In 80% of cases, it helps to return the computer control into their own hands to at least have time to keep important data.

Best Anti-Virus without installation - TOP3

1. Drweb cureit.
I use this anti-virus scanner from the moment of its creation and therefore he is number one for me! And how many times he squeezed me at work - not even count! Dr.Web Cureit! Definitely the most popular so-called online anti-virus, constantly updating and non-conflict with other antivirus software, if so is already installed on the PC. You can download it here - link.
After launch, the application will require the terms of the license agreement. And then you will see this window:

Press the "Start Check" button and the utility will hold all the necessary checks of RAM, working processes and system folders, after which the list of detected and proposal to further treat the OS will be issued.

2. Kaspersky Virus Removal Tool - KVRT
This anti-virus without installation released the main competitor of the previous program. The program is issued in the world's most famous anti-virus laboratory Kaspersky.

KVRT actions algorithm is similar to Drweb Cureit. Download the application here - link. Then run, accept the license and click the "Start Check" button. After checking, we agree with the proposed action option and wait until the infection found will be destroyed! Upon completion of the work, you will receive a report from the work program!

3. Eset Online Scanner
Currently, the ESET Online Scanner scanner is the only full-fledged online antivirus that uses cloud technologies to work. I think it is clear that to test the PC and delete viruses from it, you need to have an active Internet connection.

The utility pleased with its sizes - just over 6 megabytes against 140-150 in previous two cases. Easy downloaded here - link, easy work! Detects quite more quantity of modern virulent infection! Although users often hear complaints about his work. I use it infrequently and in the case when you need a quick check for viruses without installing antivirus, and there are no time to download the previous two solutions, or the system checking with their help did not give any results. You can download online Antivirus from Eset here - link.

Other portable antiviruses (Portable)

In general, now portable antiviruses are few, I called the best of them above, and then we will list several alternative options rather even to familiarize yourself. Using them, as a rule, does not provide significant results (well, with the exception of the domeda, perhaps), although sometimes these portable utilities are even finding and treated.

Comodo Cleaning Essentials (FREE Malware Removal Tool)

This is not just an online antivirus, and already a whole set of special utilities, which includes a portable scanner, autorun analyzers, processes, and spyware detector and Hijack Cleaner advertising modules. In principle, I can't say anything particularly bad about the dresser. Their programs used quite a lot and often. Now I use only when there is no normal alternatives at hand.

Another online antivirus from the company F-Secure, using their branded technology Lighthouse. He stands on defending Facebook - it probably says some kind of use. As for me - beautiful outwardly and weak inside. There are a lot of mistakes in work and complaints from dissatisfied users.

I treat software products from Norton, when I had to remove them with packs on client laptops. This heavy clutter monster braked the system and almost found even famous viruses. How the Symantec's pelvic evidence works - for me a mystery. I frankly dislike their products and the anti-virus scanner without installing Norton Power Eraser here is no exception. Very straining his aggressive intervention in the computer's work. Well, he would only search for viruses, so this infection also climbs the registrar. And after such fixes, you can get the non-working Windows. So if they decided to use them - be sure to put a daw on creating a backup of the registry!
And yes, often triggers normal regular programs. This can be seen in the screenshot.

Microsoft has never been seriously engaged in anti-virus software and go along this path forced circumstances. Their portable antivirus by weight is even more than Dr. Web or Kaspersky. The application works not to say to quickly - check takes quite a long time. Sometimes even something finds. If you put on the Internet - positive feedback on the Microsoft Safety Scanner scanner there is enough enough.

The work on the Internet is inevitably associated with the risk of infection with viruses, which are a kind of software or a portable code. They impede the normal functioning of the operating system using its resources for their own purposes, damage or completely destroy the data stored on the computer. The absence of any measures in the fight against malicious programs leads to the fact that the system is completely out of order, and it will be required to restore or reinstall.

There are a number of features that help answer the question of how to recognize the virus in the computer: Changing the scope of files, their extensions, the appearance of various system messages and uncontrolled sounds, reduce free memory on the hard disk, etc. To detect the viruses on the PC, developed A huge number of special programs. But none of them can provide 100% computer security guarantee. It is desirable to complement the work of the main program by various antivirus solutions - scanners and online services.

Preparatory stage
