Malicious software can establish a base on individual desktops and servers. Employing an automated mechanism to detect this type of software will aid in elimination of the software from the operating system.
Check
Verify an organizationally approved antivirus solution (Microsoft Defender Antivirus, for example) is installed on the system and in use.
Verify if Microsoft Defender Antivirus is in use or enabled:
Open PowerShell.
Enter "get-service | where {$_.DisplayName -Like "*Defender*"} | Select Status,DisplayName"
Verify third-party antivirus is in use or enabled:
Open PowerShell.
Enter "get-service | where {$_.DisplayName -Like "*mcafee*"} | Select Status,DisplayName"
Enter "get-service | where {$_.DisplayName -Like "*symantec*"} | Select Status,DisplayName"
If there is no antivirus solution installed on the system, this is a finding.
Fix
Install Microsoft Defender Antivirus or a third-party antivirus solution.
