OS failures most often occur after incorrect configuration, installation of unfinished programs, or virus infection. Loading in safe mode will show whether these problems are really the problem, and if so, help eliminate them.

How to start Safe Mode in Windows

1. Using hotkeys

• Suitable for Windows 7, Vista and XP.

Restart your computer and, as soon as the system starts to boot again, press the F8 key until a menu of additional boot options appears. When this menu appears on the screen, select the Safe Mode option and press Enter.

To exit Safe Mode, restart your computer and it will start normally.

• Suitable for Windows 10, 8, 8.1, 7, Vista and XP.

Use the combination Windows keys+ R. In the window that appears, enter the command msconfig and press Enter. When the system configurator window opens, go to the “Boot” (or BOOT) tab and check the “Safe Mode” (or SAFEBOOT) checkbox. Click OK and restart your computer.

To disable booting in safe mode, open the configurator window again, uncheck the “Safe Mode” checkbox and restart the computer.

Click on the notification icon in the lower right corner and go to “All settings” → “Update and security” → “Recovery”. Under Special Boot Options, click Restart Now.

Once on the “Select Action” screen, select “Troubleshooting” (or “Diagnostics”) → “Boot Options” (if this item is not displayed, click “ Extra options") → "Reboot". On the next screen, press the 4 key to select the Enable Safe Mode option.

To exit safe mode, simply restart your computer.

• Suitable for Windows 10, 8 and 8.1.

This method is a simplified version of the previous one. Clamp Shift key and click on the software reboot button, which you use to restart the system normally. When you get to the Select Action screen, follow the steps outlined for that window in the previous method.

To exit Safe Mode, simply restart your computer.

How to start Safe Mode on macOS

1. Using the Shift key

Hold down the Shift key immediately after turning on or restarting your computer until you see the login window.

To exit Safe Mode, simply restart your Mac without pressing any additional keys.

Open Finder → Programs → Utilities and launch the Terminal utility. Type sudo nvram boot-args="-x" and press Enter. After this, restart your computer.

To disable booting into Safe Mode, launch Terminal again, type sudo nvram boot-args="" , press Enter, and restart your Mac.

What to do next

In safe mode, only the standard set services, drivers, settings and programs. If everything works fine, then there is probably something wrong with third party programs or recently changed OS settings.

In this case, you need to scan your computer with an antivirus and remove suspicious software directly in safe mode. If this does not help, you should consider restoring macOS to normal.

If problems with your computer occur in safe mode and even restoring the OS does not change the situation, most likely there is something wrong with the hardware. First of all, make sure that the components do not overheat and, if necessary, clean the computer. If the temperature is normal, contact the service center.

If you are reading this article, you are probably asking yourself a question about how to disable Kaspersky self-defense if your license has expired and the self-defense menu item is not active, i.e. nothing can be changed about it. This article will help you disable self-defense in order to make and receive a new key.

How to disable self-defense if you don't have a license

To begin with, it’s worth saying that there are two ways to do this, one way is to remove Kaspersky Anti-Virus, and the second is to loading Windows in safe mode. In fact, both methods will ultimately give the same result. I'll start by telling you something more accessible to ordinary users method by uninstalling the program.

2. Let's launch this program and agree to the license agreement.

After removing Kaspersky, click OK and restart the computer.

In the line that appears, enter the command regedit and click OK.

Before us is the editor Windows registry. Now here you need to delete some keys (folders). They are located at:

HKEY_LOCAL_MACHINE\SOFTWARE\ KasperskyLab

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SystemCertificates\ SPC

Those. use it as an explorer, but you need to delete it at the above “folder” addresses KasperskyLab And SPC, to do this you will need to click on them right click mouse and select " Delete".

4. After you have completed deleting these keys, we close the registry editor and now download the desired Kaspersky product from the official website Kaspersky Total Security or Kaspersky Internet Security, install the downloaded Kaspersky antivirus and launch it. After which we see that the program asks to enter license key or get a trial version, in which case the self-defense tab will become active again and can be turned off.

The second way to disable self-defense if you don’t have a license

It consists in the fact that you need to reboot the computer into safe mode, already in safe mode and do the same operations starting from paragraph 3 this instruction. Those. you won’t need to uninstall Kaspersky before going into the registry. Those. launched in safe mode, deleted the same keys in the registry and rebooted in normal mode, after which we gained access to the blocked self-defense.

The video below clearly shows the process of disabling blocked self-defense, and you can visually evaluate these manipulations; in fact, everything is very simple.

None today Windows user can't do without an antivirus. After all, every day all sorts of attackers try to gain access to personal data or simply mischief ordinary users. And the creators of antiviruses also have to improve their products every day so that they can defeat absolutely all possible threats.

One of the best antiviruses today is Kaspersky Internet Security . This is a truly powerful weapon against viruses! For many years, Kaspersky Internet Security has held the title of a real heavyweight in the war against them. No other antivirus can match it in the way it fights all kinds of threats. Yes, today there is Avast Free Antivirus, Nod32, AVG, and many other antiviruses. But after using Kaspersky Internet Security once, users usually do not want to switch to something else. And all thanks to truly reliable protection provided by advanced technologies in the fight against virus threats.

Kaspersky Internet Security instantly scans all files, programs and sites on the Internet that the user visits. If any threat occurs, a message immediately appears indicating the presence of the threat, as well as ways to solve it. This way, the infected file can be deleted, disinfected, or quarantined.

If a user visits a site that poses a threat and contains virus programs, Kaspersky Internet Security informs him about this directly in the browser window. In this case, the person simply will not be able to access the site, because the program will block him. It is worth saying that erroneous identification of sites as malicious is extremely rare.

The results of continuous monitoring of programs and the network can be seen by clicking on the " Additional tools" in the main program window. Here in the diagrams you can see the memory and processor load, as well as the amount of information received and sent to the network. It also displays a general report on the work of Kaspersky Internet Security - how many threats were neutralized, how many network attacks and programs were blocked for the selected period of time.

Anti-phishing protection

Internet scammers who create fake websites to trick people into entering personal information, including payment information, are not a problem for Kaspersky Internet Security. This antivirus has long been famous for its anti-phishing system, which will not allow a person to go to a fake site and leave their data somewhere. Kaspersky Internet Security has its own unique criteria by which the program can recognize a phishing site or phishing attack, as well as the databases of such sites.

Parental control

Kaspersky Internet Security has a very useful protection system for parents whose children also use their computer. You can access this system from the main program window. It is protected by a password that parents enter upon first launch parental controls.

This system allows you to block access to certain programs for a certain time or allow the computer to be turned on only for a certain period of time, for example, one hour. Parents can also make the computer take breaks at certain intervals, for example, every hour. These options are available separately for weekdays and separately for weekends.

All of the above functions are available in the “Computer” tab of the parental control system. In the “Programs” tab, you can restrict the launch of games and programs for users under 18 years of age. There you can also configure different categories of programs, each of which will be launched only for certain users.

In the “Internet” tab, you can limit Internet access to a certain value. For example, the Internet will be available only for one hour a day. You can also limit visiting sites for adults, sites that contain scenes of violence and other content that is not necessary for children and, in general, for all people without mental disabilities. There is a safe search function here that will prevent the user from finding information with this very content.

The “Communication” tab allows you to prohibit communication with specific contacts from social networks. For now, you can add contacts from Facebook, Twitter and MySpace here.

Finally, in the “Content Control” tab, parents can set up real surveillance of their child. This way they can know which words he uses most often when communicating with other people and in search queries. They may also prohibit the transfer of anything related to personal information to third parties. Here we're talking about about bank accounts, addresses and similar data. It works very simply - if a child writes a message to someone, for example, the number of the parent bank card, it is automatically erased.

Making secure payments

Kaspersky Internet Security has a very effective system for making secure payments. In theory, it works simply; for attackers, intercepting personal data becomes an impossible task. When a user makes a payment, their payment information is temporarily stored on the clipboard. This is where the Kaspersky Internet Security system begins its work - it additionally encrypts all information in the buffer.

In more detail, the secure payment system makes it almost impossible to take snapshots while data is being transferred. This is exactly the technique that attackers use to access personal data that is in the buffer - they simply photograph the screen using software. But the combination of the hypervisor, DirectX® and OpenGL makes this procedure almost impossible.

This system starts automatically. And when you open the site payment system the user will see a message asking him to open the site in a so-called secure browser, that is, using this very secure payment system. By clicking on the appropriate button, the user will start operating the system from Kaspersky Internet Security.

Privacy protection

Nowadays, small programs that end up on the computer are also common. regular user and begin to collect all information about him, including payment information. Attackers also try to gain access to the webcam to find out more information about their victim. So, the “Privacy Protection” function in Kaspersky Internet Security will not allow them to do this.

And so that they do not have a single chance to commit their evil deeds, the program can also delete log data, cookies, command history and all that information from which personal data can be taken.

To get to this menu, you need to click the “Additional functions” button in the main program window.

Safe Programs Mode

In the same menu additional functions mode available safe programs. If you enable it, then only those programs that are listed in the Kaspersky Lab database as those that can be trusted will be launched on the computer.

Protection on all devices

By logging into My Kaspersky, you can ensure protection on your smartphone, tablet and netbook. Moreover, all this can be managed via the Internet using remote access. This function is available after going to the “Online Management” tab in the list of additional functions.

Protection from the cloud

This technology allows users to record information about emerging threats in the cloud so that others can deal with it faster. All information about emerging threats and viruses immediately falls into cloud storage, is checked for information about it and entered into the database. This approach allows you to update the virus database online, that is, instantly. Without cloud-based protection, virus databases would be updated manually, allowing new viruses to infect the computer without the antivirus's knowledge.

There is also information about websites in the cloud. It works very simply - a person goes to the site and, if it is safe (no threats have arisen, no virus has entered the computer, etc.), then the database is recorded as one that can be trusted. Otherwise, it is recorded in the database as not trusted, and when another Kaspersky Internet Security user visits it, he will see a message about the danger of this site.

Search for system vulnerabilities

Part of the Kaspersky Internet Security program allows you to check your system for vulnerabilities. During the scan, absolutely all files will be checked. The programs will look for code fragments that are unprotected and through which attackers can gain access to data or a virus can enter the computer. This code will be further protected or the file will be deleted if it is not needed.

Recovery after infection

After the computer has been subjected to virus attack, Kaspersky Internet Security can scan for damage caused by the virus and repair it. Some files will have to be deleted, but in most cases it will be applied special system, which allows you to restore damaged files, referring to their past versions recorded in the system.

Support

Any user can get help from a Kaspersky Lab operator or read about their problem in the database. To do this, just click on the support icon in the main program window. There you can also read recommendations for setting up the program and chat with other users on the forum.

Customizable

In the Kaspersky Internet Security settings window, you can not only change the password and disable some program functions, but also start a power saving mode or otherwise achieve less consumption of computer resources. For example, you can make sure that when you start your computer, only the most important parts of Kaspersky Internet Security are launched, and not all at once. This approach will allow you to gradually use your computer's resources, rather than immediately putting too much stress on the system.

Another interesting approach is to perform the main tasks of the program while the computer is idle. This means that when the user works with big amount other programs, only real-time protection will work in Kaspersky Internet Security. Everything else will be disabled and the update will not run. All this can be configured by clicking on the settings icon.

Advantages

1. Very powerful protection against all kinds of viruses and spyware.
2. A large number of additional functions, such as making secure payments and parental controls.
3. Wide range of customization options.
4. Russian language.
5. Customer support is good.

Flaws

1. Despite the use of different approaches to reduce the load on the computer, on weak machines Kaspersky Internet Security still greatly slows down the operation of the entire system.

Today, Kaspersky Internet Security can rightfully be called a very serious threat to attackers. This is a real warrior in the fight against viruses, who will truly fight with all possible means against all kinds of threats to the security of a particular computer. Kaspersky Internet Security has a paid license, but you can pay for such wide functionality and truly high-quality virus protection. Therefore, if reliability is important to you, choose Kaspersky Internet Security.

How to turn off safe mode on Windows 10 and turn it on Kaspersky protection Internet Security 2016? and got the best answer

Answer from Strannik[guru]
Hello. If I understand correctly, then you checked the “Safe Mode” checkbox in msconfig-boot, correct? If so, then: This did not need to be done because now the PC will always boot in this mode. You just needed to restart your PC. This reboot window appears when the user, having just installed the antivirus, opens secure browser or virtual keyboard, and for them to work you need to restart the PC (once).
Go to msconfig-boot and uncheck "Safe Mode"
After restarting the PC, open the antivirus and make sure that the antivirus reports that the PC is protected (this is displayed in the main window). Report the result.

Hello! Here is a selection of topics with answers to your question: How to disable safe mode on Windows 10 and enable Kaspersky Internet Security 2016 protection?

There is no doubt that one of the most important programs on a computer is an antivirus. Even one “accidentally” virus that gets onto your PC can make working on it unbearable! Besides, it would be “good” if the virus simply showed an advertisement, but there are viruses that can destroy dozens of files on a disk (which may have been worked on for months).

About 10-15 years ago the number of antiviruses was relatively small and the choice was limited to about a dozen. Now there are hundreds of them!

In this article I want to focus on the most popular today (in my opinion). I think that many people will find this information useful for cleaning and protecting their home PCs. And so let's get started...

Kaspersky Anti-Virus

I’m not afraid to say that Kaspersky Anti-Virus is the most famous and popular anti-virus in the post-Soviet space. Kaspersky's antivirus database is truly huge. It easily catches all possible viruses available on the network. But, just as the developers did not announce acceleration and, most importantly, a radical reduction in computer resources, they did not complete this task.

Kaspersky Anti-Virus, as it slowed down the PC before, continues to do so now. Moreover, using it on a fairly powerful machine does not save you from slowdowns - Kaspersky’s gluttony is limitless, this can only be corrected by very careful tuning of the program.

New in Kaspersky Free Antivirus 2017

Kaspersky Free Anti-Virus 2017 has the following new features:

• Improved program update in background. Now when updating you do not need to re-accept the terms License Agreement, if it hasn't changed.
• Improved Mail Anti-Virus. The default depth of heuristic analysis has been increased to medium level.
