For example, a hacker may put spyware that runs in a stealth manner and provides access to a hacker inside your computer or network.

The symptoms of any corruption in Windows is recognized by the abnormal behavior of computer files or account-

  2. The computer runs out of memory even when few programs are running.
  3. Many programs become too slow to open and execute that was working fine until recently.

Windows 10 has accumulated all the possible threats that can occur in the system and crash it beyond repair. So, you should use several security features that will protect you from attacks in advance.

The Windows Defender Smart Screen stops the threat at first sight. It forbids the users from opening a website that is termed ‘malicious’ or stops such downloads that do not clear its filter criteria. It fights against scamming sites, phishing, fake ads, and drive-by attacks.

User Account Control

User Account Control makes the management of the whole computer much better by running all the applications and tasks under a security context. It checks that which application is authorized by the user and which is not. So, malware or spyware will not even start and corrupt the stem. Although, the administrator can check the filter and allow safe-looking and healthy processes. It reduces the chances of accidental changes to a minimum.

Windows Defender Application Guard

Windows Defender Application Guard provides security to Microsoft Edge Web Browser. It uses Hyper-V Virtualization technology to whitelist the site and show them as trusted sites. When the site is not trusted, then Application Guard opens it in a secure container excluding access to memory, store, endpoints, and other applications.

Microsoft Bitlocker

It is a full-end encryption solution provided to Professionals and business enterprises. It expands the file and system protection and makes the data inaccessible when the computer is decommissioned.

Windows Defender Credential Guard

Defender Credential Guard provides software access to only privileged users. It uses virtualization-based security to assess the rightful users who are authorized by the administrator to run some programs. For example, in a shared computer, the administrator can block some users from running Exchange Server.
