Windows 10 has Windows Defender pre-installed. It aims to protect the user's PC from the most common viruses. It does not fully replace the antivirus, but during the execution of any action, it alarms the user with notifications.
For example, notifications about how many files were scanned, whether viruses were found, and so on. In most cases, this information is simply useless. You can disable these annoying notifications:
1. Open Windows defender Center.
2. Click "Settings" (the gear icon at the bottom left).
3. in the window that opens, disable the first parameter "Get recent actions and scan results".
Windows defender notifications will no longer bother you. However, all critical notifications will be displayed in any case. For example, if the scan still found a virus.
