Hi,

We will possibly have to use the big gun.

I need to know first if you can enable the Recovery Environment...

Open FRST on the compromised computer:

copy/paste the following inside the text area of FRST. Once done, click on the Fix button. A file called fixlog.txt should appear on your desktop. Attach it in your next reply.

Start::
CMD: bcdedit.exe /set {bootmgr} displaybootmenu yes
CMD: bcdedit.exe /set {default} recoveryenabled yes
End::

On completion, a message will come up saying that the fix has been completed and it'll open a log in Notepad
Copy and paste its content in your next reply.

Wait for further instructions.

Yes.

Please read carefully.

You will need access to a spare PC and a USB flash drive that has not been in contact with the sick PC...

Lets proceed:

Preparing the USB Flash Drive

Boot up your spare PC:
Plug in the flash drive, navigate to that drive, right click on it direct and select format. Quick option is adequate.
If the Flash driver is new this may not be required.

Next,

On that same PC download the right version of Farbar program for your system to Desktop or the Flash drive.
64-bit or 32 bit version. Select the one you need.
https://www.bleepingcomputer.com/download/farbar-recovery-scan-tool/

If the files were saved on the Desktopl Move the executable (FRST.exe or FRST64.exe) to your USB Flash Drive

https://support.microsoft.com/en-us/help/827218/how-to-determine-whether-a-computer-is-running-a-32-bit-version-or-64

Do not plug Flash Drive into sick PC until booted to Recovery Environment.

===

Boot the compromised PC to Recovery Environment, if you are unsure of that action have a read at the following link, maybe bookmark for future reference...

To enter the Recovery Environment with Windows 10, follow the instructions in this tutorial on TenForums https://www.tenforums.com/tutorials/2294-boot-advanced-startup-options-windows-10-a.html

From the Windows 10 Tutorial you should get access to the Advanced Startup Options at boot for Windows 10

Select in this order
"Troubleshoot" > "Advance Options" > "Command Prompt"

Once in the command prompt

Plug your USB Flash Drive in the infected computer

In the command prompt, type notepad and press on Enter
Notepad will open. Click on the File menu and select Open
Click on Computer/This PC, find the letter for your USB Flash Drive, then close the window and Notepad
In the command prompt, type e:\frst.exe (for the x64 version, type e:\frst64.exe and press on Enter
Note: Replace the letter e with the drive letter of your USB Flash Drive
FRST will open
Click on Yes to accept the disclaimer
Click on the Scan button and wait for the scan to complete
A log called FRST.txt will be saved on your USB Flash Drive. Attach it in your next reply.

p.s.
If at any time you need additional information please ask before proceeding.

Post the Fixlog.txt and the FRST.txt logs for my review.

Wait for further instructions.

I try wait a bit, and restart several time to see if it coming back, no new "msiexec64.exe" created, it seem to be fix. hmm.... can you give me the command for FRST to disable boot menu on startup pls? I do know that recovery environment are  enabled by default(probaly) so I could leave that one on.
