Solution

Click Start -> Run -> type regedit and click OK.

Go to the following registry key:

For each of the following sub keys, verify the Start value exists within the key, and contains the data shown:

Note:

​This problem may be related to McAfee running this versions:
McAfee Agent Version 5.0.1 and above
McAfee Virus Scan 8.8 patch 5 and above

This problem occur after SysCore 15.3 or later is installed

Solution:

There is several solution that I tested

1. Restart the system and start in Safe Mode, after a successful login restart the system normally

2. From ePO change the Access protection policy (Part of Virus Scan):
- Disable the Access protection Policy for the affected systems
- make sure the system received the policy and the access protection is Disable
- Restart the system
- after a successful login Enable the access protection policy from ePO

Problem:
After installing Virus Scan Enterprise 8.8 Patch 5, The Access protection Rule are empty.

Solution:

Enabled 8.3 on volume using: 

1. Open Command Line(CMD)  
- run the command "fsutil.exe 8dot3name set D: 0"
Note: D is is the volume where ePO is installed.


2. open registry (From command line\run click regedit)HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem
change the value of "NtfsDisable8dot3NameCreation" to 0

rebooted system
removed extension and then checked it back in. (before removing the extension. 
Please export, VSE poilcies/policy assignment, client task/client task assignments)
re-imported policies and extensions

Problem: Multiple McAfee Virus Scan icons are displayed.

Solution 1:

Uninstall and reinstall(restart between the action is recommended)

Solution 2:

Go to unaffected system, open the registry (from the run command "regedit") export the the registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\McAfee\DesktopProtection\LicenseInformation

Go to affected system and run the file from the unaffected system, click OK when ask.

Problem:

Always On Access and Access Protection modules are disable and also McAfee McShield and McAfee Validation Trust Protection services are stopped and can't be started.

Solution:

Click Start, Run, type regedit and click Ok.

Go to those paths:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\McShield
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\mfevtp
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\mfehidk

Do the following to all paths:

1. If there is no Start value, right click a blank space and select New, DWORD value, and name it Start
2. Right-click the new Start value, select Modify, and ensure that the Value data is set to 0 (zero). Change it if necessary
   
3. Restart the system
