Windows 10, like Windows 8, has a built-in antivirus that provides real-time protection. It automatically runs in the background, which guarantees a basic level of virus protection to all Windows users. Thanks to this, Windows 10, unlike Windows 7, does not pester with a request to install an antivirus.
Those who used Microsoft Security Essentials in Windows 7 and previous versions of the system, the new antivirus is already familiar. This is the same basic program, simply renamed to Windows Defender (Windows Defender) and included in the operating system since Windows 8.
Auto scan and update
Like other antivirus applications, Windows Defender automatically runs in the background, scanning every file before opening it. You don’t have to remember about him at all. Defender attracts attention only if he detects malware.
At the same time, he does not even ask what to do with the find, but automatically removes viruses and sends files to quarantine. A message simply appears that malware has been detected and Windows Defender is taking steps to remove it or that it has already deleted all detected threats. The message is saved in the notification center.
Anti-virus database updates are installed automatically through the Update Center (Windows Update), without requiring a reboot. The user does not need to worry about updating Windows Defender.
Setup and exceptions
Windows Defender settings are located in the Settings interface. To get there, open the Start menu and click on the Settings link. Select the Update and Security section (Update & security) and then Windows Defender.
By default, Windows Defender automatically provides real-time protection, cloud protection, and sample sending. Real-time protection means that the program constantly scans the system to detect malware. This feature can be turned off for a short time if you want to increase system performance, but then it will be automatically turned on again to guarantee protection in the future. Cloud protection and sending samples allow Windows Defender to exchange information about threats and detected malicious files with Microsoft servers.
Here you can configure exceptions. to do this, scroll through the page and click the “Add an exclusion” link. Exceptions can be made to specific files, folders, file types, and processes. If the antivirus greatly slows down the guaranteed secure application, you can add it to the exceptions to improve performance. However, you should not abuse exceptions. if you do not approach the matter wisely, this can weaken the security of your computer, because Windows Defender will simply stop checking certain places.
If you scroll down the settings page to “Version info” and click on the “Use Windows Defender” link, the antivirus desktop interface will open. Those who previously used Microsoft Security Essentials will recognize it right away. (In the future, however, Microsoft will probably transfer other settings from here to the Options interface.)
In this window, you can run a quick scan, a full scan or a selective scan of specific folders. You can, for example, conduct a special check of an external drive connected to a computer.
Manual antivirus scans are not required regularly. In any case, Windows Defender scans everything in the background and does a full scan of the computer on a schedule. So the ability to run a scan manually is relevant only for scanning external media and network folders.
If Windows Defender reports malware blocking, you can view the locked files in the desktop interface of the antivirus. Click the “Use Windows Defender” link in the “Settings” link above, and in the window that opens, go to the “History” tab. Click the View details button to see a list of blocked programs. It indicates the name of the malware, the date it was detected and quarantined.
Here you can completely remove the malicious program from the computer or allow the launch of files that Windows Defender considered dangerous. This should be done only if you are one hundred percent sure of the mistake. If not, do not run quarantined files.
Install another antivirus
When installing another antivirus, Windows 10 automatically disables Windows Defender. It stops scanning the system in real time, so conflicts between two different antiviruses are excluded. If you open the Windows Defender settings after installing another anti-virus program, all options will be inactive, and when you click the "Use Windows Defender" link, a message appears stating that it is disabled. The message will say that the application is disabled and does not monitor the computer.
After removing another antivirus, Windows Defender will work again to ensure uninterrupted anti-virus protection.
Regardless of which antivirus you prefer, it’s nice to know that from now on every Windows installation has built-in antivirus protection. Still, the Microsoft Malicious Software Removal Tool, which is distributed monthly through the Update Center, does not replace a full-fledged antivirus.
