Hi Mitchell McGee,
Welcome to Microsoft Community.
Based on the original description, it seems that McAfee's full virus scan affected the state of certain processes or services.
Would you mind sharing more information about this issue with us?
- Were there any special events in the device before the problem occurred? For example, system update, driver update, application update, BIOS update?
- Is this phenomenon limited to full virus scan performed with McAfee?
- Is it the same when you run a scan in a relatively clean environment (for example, new local account, clean boot)? Create a local user or administrator account in Windows - Microsoft Support Clean Boot starts Windows with a minimal set of drivers and startup programs. It can be used to determine whether a background service or program is interfering or causing a problem. These steps of "clean boot" might look complicated at first glance. However, to avoid any trouble for you, please follow them in order and step-by-step. Please be careful not to disable any services related to security credentials or security authentication, such as TPM, Security, Credential.
- Are there any event logs recorded in the device that related to the phenomenon? Event Viewer | Microsoft Learn
- If possible, would you mind sharing with us a video file visualizing the phenomenon? Visual content helps to understand the problem state more intuitively and reduces errors at the comprehension level.
