Microsoft has developed its own antivirus - Defender, which is distributed as part of the Windows 10 OS. Unfortunately, it cannot boast such extensive databases as paid competitors, but it is enough for ordinary users. If your antivirus is disabled after the update, you can easily restart it manually. This article describes how to turn on Windows Defender 10. At the end of the article, you can watch a video with instructions on how to set up Windows Defender for versions 7 and 8.

Kaspersky Antivirus is one of the best paid antivirus programs. But sometimes there are times when you spend your money, buy a license, install it and at first everything works perfectly, but then after a while Kaspersky stops running.
Do not immediately blame the whole world for your problems, curse the antivirus and ask yourself the question: why did I buy it? Perhaps you simply removed it from startup, and therefore it stopped automatically loading into you along with your OS. Fixing it simple addition antivirus to autoload. You can use the "msconfig" command and then add your Kaspersky to startup, and then restart the PC.
If it's not about autoloading, then most of all your antivirus attacked a large number of viruses that corrupted the files and disabled it. In that case, you don't have to worry either. We try to remove the infection with the help of another, one-time antivirus or some utility (for example, Malwarebytes Anti-Malware). Next, reinstall your Kaspersky. You can also use official utility Kaspersky, completely remove your antivirus, and then reinstall it. All this must be done in safe mode. After reinstallation, at the first start, we run a PC scan and remove all viruses.

What to do if nothing helped?
You need to do certain work over your system. We suggest you do this in two steps.
1. Update drivers from driver booster 3 . This is really cool software that often helps! Upgrading old drivers to new ones is very important. You may think that Windows itself lets you know when new updates are available.
Yes, sometimes it shows alerts, but mostly only for Windows updates or sometimes also for the video card. But besides this, there are many more drivers that need to be updated regularly.
2. Repair PC with Reimage Repair. Run this program to analyze your system for errors (and they will be 100%). Then you will be asked to cure them, both individually and all at once.
} ?>One of the most effective antiviruses in our time is considered a product from Kaspersky Lab. It is precisely because many use it that questions about its malfunctions arise quite often. The direction of this topic can be very different, but today it is worth dwelling on one of them in detail.
In particular, when the antivirus simply does not start, and this can happen on any operating system. To correctly determine the cause of such an error, you must first fully analyze all your previous actions that could lead to this. The user is able to fix all these problems on his own, so there is nothing serious about this. So, let's start with the most common.
Change operating system
Now we are not talking about a complete reinstallation, because in this case, the antivirus is simply removed. Everything is based on system updates that are regularly offered to Windows users. After all, all licensed copies were offered to switch to the new "ten", with its release, and earlier in the same way it was possible to get the "eight". In some cases, the system even updated itself without asking the user about it. After launch updated system most applications work stably, but Kaspersky is not one of them, such a climate change is beyond its power. To solve this problem, in this case, it is recommended to simply reinstall the program. During new installation the antivirus will configure itself to work with the new system correctly; unfortunately, it cannot be updated along with others.
Recovery
In the case of long-term use of one operating system, it becomes cluttered over time. Various minor problems can harm the work of such a gentle antivirus. To eliminate the causes, you should try to roll back the system a few steps back. Moreover, this method can also help if other programs or games fail to launch, so keeping it in your arsenal will not be superfluous. To fulfill this procedure in the seventh version, you need to visit the "Start" menu, select "All Programs", "Standard" and the corresponding recovery partition. Recovery can provide an effective solution in half of the cases of failure of the antivirus. Of course, if the reason is related to this. Therefore, when it becomes clear that the method did not solve the problem, the antivirus should be reinstalled. You can reinstall immediately, without looking for other ways, because this is the most effective, but, as a rule, it does not give a full guarantee.
Incompatibility
This reason lies in simultaneous use several antivirus products. For the desire for complete security some users do not think about how much they load the system with this. In addition, not all antiviruses are able to work in parallel, most often there is a conflict between them. All their resources will be spent on fighting a competitor, not system threats, so you should think carefully before making such a choice. By the way, a similar reaction of the antivirus can be on other programs. If it stopped working after installing new software, then you will have to sacrifice something for further work. Either remove the new program, or replace the antivirus itself. In the case of several antiviruses, you will have to leave only one so that it can spend its resources exclusively for its intended purpose.
not to meet similar problem you should not install several anti-virus programs on your computer, because each of them consumes them great amount and together they will not allow the system to work at full capacity, even if there is no conflict, which is very rare. If you really want to get more security, you can install anti-spyware, such as SpyHunter, in addition to Kaspersky.
Infection
Oddly enough, but this can happen due to the presence of viruses in the system. Some of their upgrades are trying first of all to eliminate their fighter, and then calmly walk around the entire system. Since the antivirus itself loses its performance, you should remove it and immediately reinstall the operating system. This is the only way to get rid of malware on your computer. The thing is, if you just install new antivirus it will not give a full guarantee of detection, and it may also be "eaten".
Other incompatibility
We return to the first point of the update and now we will consider the update of the system to the tenth version in more detail. Here everything is much simpler, or more difficult how to look. The fact is that Kaspersky simply cannot work on the new version of the operating system, so even reinstalling it will not help in this case. This system is simply incompatible with the antivirus from Kaspersky Lab. There is no way to fix this problem until Microsoft releases a patch that solves the problem. That is why many users refuse to use new operating system in favor stable operation your antivirus, especially if it is paid.
No license
The failure may be related to the installed pirated version. This applies to the antivirus itself and to the operating system. If you install a non-licensed antivirus, you can simply try to reinstall it, but if the problem is in the operating system, everything is much more complicated. It is simply impossible to install a licensed antivirus on a “pirate”, or rather, it can work for some time, and after stopping it will not start again. You can try to use a similar unlicensed version of the antivirus itself, or change your operating system to a licensed one. You can just install another antivirus. What exactly is suitable for the user is up to him to decide, but all the problems of troubleshooting the antivirus are solvable, and on their own.
If you do not have Kaspersky installed, it may not be in the system. This antivirus is compatible with almost everything Windows family A: It works on 7, 8, 10, Vista and even XP. And computer resources do not affect the download process. It depends on them how the utility will work.
Reasons for failure installation of Kaspersky may be very different
Finding out why Kaspersky won't load isn't easy. After all, the reasons for the failure can be different.
You should not install several different antiviruses. If the system has two firewalls, this does not mean that the protection will be twice as good. On the contrary, a large number of such programs will lead to crashes, errors and brakes. It is better to choose one Antivirus and use only it.
To install Kaspersky on Windows 7, 8 or 10, get rid of other antiviruses. Otherwise, they will conflict with each other. You can only leave portable applications(for example, a utility from DrWeb).
If you move Antivirus to the trash or delete it directly using Delete key, nothing will work. You must use your own utility uninstaller or built-in Windows tools.
- Go to "Control Panel".
- Open the Uninstall Programs menu (or Programs and Features if you have icon view enabled).
- Find your antivirus in the list that opens.
- Click on it right click mouse and select Delete.
- Follow the further instructions of the install/uninstall wizard.
- Restart your computer.
For some defenders special "cleaners" are made. They not only remove the program, but also erase all traces of it: shortcuts, temporary files, configurations, saved libraries, registry entries. Such uninstallers can be downloaded from the official website of the software developer.
If removing all defenders did not help, and the desired antivirus is still not installed, then the reason is different.
Previous version not fully removed
If you incorrectly uninstalled the previous version of Kaspersky, the new one will not be installed. Let's say with Kaspersky Anti-Virus 10 you decide to upgrade to 15. Or you just want to reinstall your antivirus. Before that, it must be completely erased. Not just transfer to the trash, but remove all data associated with it.
If you remove Kaspersky with standard Windows tools, files, keys and links may remain from it. Therefore, you need to download the program - uninstaller.
- Go to the kaspersky.com website.
- In the search bar (top right), type in the query "kavremover".
- In the results there will be links to download the product "Kzip" and "Kavremvr.exe". The first is the archive with the uninstaller, the second is the uninstaller itself. You can choose any download option.
- There is also an instruction describing how to properly remove the antivirus.
- If you took the archive, unzip it.
- Run the executable.
- Accept the license agreement.
- A captcha window will appear. If you can't see the symbols, click on the button with circular arrows. This will change the picture.
- In the "Products found" drop-down list, select the version of the antivirus you want to erase.
- Click on "Delete".
- After the process is complete, restart your computer.
- A log in .TXT format will appear in the directory where the uninstaller is located. It can be opened in notepad.
- Check if Antivirus is installed.
Software incompatibility
Kaspersky works with different versions of Windows. But this does not mean that one installer is suitable for both 10 and XP. If you try to download an outdated antivirus on modern system, nothing will work.
- To fix the problem, download the latest version of the installer from the official Kaspersky Lab resource.
- Open the site.
- Click the Home tab (or Business if you're looking for a corporate antivirus).
- Select the appropriate product in the column on the left.
- There is a "System Requirements" section. It lists the supported OS.
Can be made easier:
- Hover over "Download".
- Item "Distributions".
- Click the right antivirus.
Kaspersky for older systems can be found online.
Installer corrupted
If Kaspersky is not installed on Windows 7, 8 or 10, the problem may be in the installer itself (it is damaged or contains errors). This happens if the download of the file is interrupted, and it is not fully loaded. But most of the time it's the fault unlicensed software. Paid programs hack. Sometimes inexperienced people do it. And the result is a non-working EXE file.
There are two exits:
- Install the licensed utility. She definitely won't be buggy.
- Try downloading the hacked app from another source.
Issues with .NET Framework
For Kaspersky to work stably on Win 10, 8 and 7, it needs a .NET utility Framework version 4.0 and above. This program should already be in Windows. But if it functions with errors, you need to update or reinstall it.
- Go to Microsoft.com.
- Enter "Microsoft .NET Framework" in the search bar.
- In the Downloads section, select the latest version of the utility.
- Click on the red "Download" button.
Download .NET Framework version 4.0
- Run the resulting file.
- Wait until the end of the process.
Check if the antivirus is installed. If not, try completely uninstalling Framework and redownloading it.
There is a virus in the system
Another possible reason is that the system is infected with malware. It is this that "does not let" Kaspersky. The DrWeb utility will help get rid of the virus. It does not need to be installed or removed. it portable program, which is suitable for Windows of all versions (XP, 7, 8, 10).
- Go to the site "drweb.ru".
- Download tab.
- Scroll down the page to the "Free" section.
- Open "Dr.Web CureIt".
- Download button.
Click on "Download for free"
- Run the downloaded file.
- Click "Scan objects".
- Check all checkboxes.
- Click on "Start Check".
- It will take some time.
- The program will display a list of suspicious data. Folders will be listed in the Let column. You can choose which files to delete. If you know for sure that the object is safe, select Skip.
It is best to check in safe mode. To enter it, when you turn on the computer, press the F8 key. Options for starting the system will be offered. So the virus will not be able to "hide".
Other reasons
If Kaspersky is not installed on Win 7, 8 or 10, then:
- It doesn't have enough hard drive space. Delete unnecessary programs and data so that Kaspersky can work safely.
- There is some incompatible data. Try creating a different Windows account. And already put Antivirus in it.
- You didn't restart your computer after you uninstalled another antivirus.
- In the register there were entries from the old defender. Use the app to clean and fix keys and links. For example, CCleaner or Registry Fix.
- System requirements do not match. Try to install the old version of the utility.
- You made a mistake when entering the license key.
Kaspersky is reliable protection from malware. It is also suitable for large organizations, and for ordinary users. And it's a shame when Kaspersky is not installed on Windows 10, 8 or 7. But the reason why the defender does not load on the computer can be eliminated. Then you can use the antivirus.

Hello dear blog readers. Protecting your computer from viruses is no longer just a necessity.
This is a mandatory measure that will allow you to protect your data from damage and theft. The first step to protecting against viruses is to become familiar with how they work. To God forbid not to get caught. I wrote about this in an article -.
We will carry out all operations using the example of Kaspersky Anti-Virus 2012. A lot of water has flowed under the bridge since the first version of this anti-virus. And initially this antivirus was, to put it mildly, far from ideal.
Kaspersky has changed a lot for recent times and now it can rightfully be called one of the best antiviruses for computer. Today we deal with already enough powerful tool in the fight against computer viruses. Antivirus has always been paid, but like every similar company, there are trial versions which can be downloaded from . Choose the trial product you are interested in and download it.
Before running the setup application, you must do the following:
- Close all windows of running programs;
- If your computer already has incompatible third-party software or similar various anti-virus programs installed, close and uninstall them.
1.1 Updating databases and configuring antivirus
Any antivirus needs to be updated periodically. Regular updates allow the antivirus to keep track of the most latest versions viruses.
To update Kaspersky Anti-Virus, just open the main program window and click the update button.
After the update, you need to make sure that the antivirus protection is configured as efficiently as possible. To do this, pay attention to the monitor icon in the main menu of the program. There are three types of icons in total.
There are times when you need to disable your antivirus, but not everyone knows how to disable the antivirus? The problem is that they are all programs from different manufacturers and installed on different operating systems.
Developers of anti-virus programs specifically make it difficult to disable their product, but this is not done out of harm, but so that they cannot be disabled by viruses and malware. This makes protection as effective as possible.
Before you disable your antivirus, you should understand that your computer will be in danger.
Disable any antivirus
In order to disable the antivirus, you need to go to the "Control Panel" through the "Start" menu.
Now in the "Control Panel" you need to find an item such as "Administrative Tools" and go to it.
Before turning off the antivirus, you must select the "System Configuration" item. This is where the shutdown process will take place.
In this menu, simultaneously in the "Startup" and "Services" tabs, you must uncheck the boxes in front of the name of your antivirus program. Click "Apply".
A menu will appear where you need to restart the computer, after which it will start with the antivirus turned off.
Why turn off your antivirus?
There may be several reasons: some sites do not load, programs do not open, especially “activators”, etc. Moreover, they may not be malicious or viral, but the program will detect them that way. Some people turn off the antivirus for the period of games in order to use the full performance of the computer, but how to turn off the antivirus for a while? Very simple.
Many antivirus programs have a disable feature in their system. This is much easier and more convenient, because it does not have to reboot.
Before temporarily disabling the antivirus, you need to make sure that it has such a function. For example, Avast has it. To do this, we find the icon of your antivirus in the tray and after clicking the right mouse button, select "Manage antivirus screens" and mark the required period of time.
Be that as it may, even disabling the anti-virus program for an hour suggests that any virus can have time to penetrate the root of the system and start destroying files. If you still need to do this, it is best to first disconnect your computer from the Internet and local network.
