MacBook Pro periodically suddenly turns off.

MacBook Pro 15'' Mid 2014 suddenly turns off.

My results:

1) Battery replacement - doesn't solve;

2) Replacement of thermal paste - doesn't solve;

3) Installation of a clean OS X - doesn't solve;

4) Cooling - doesn't solve;

5) New High Sierra - doesn't solve;

Noticed:

1) Turns off more often after several hours of operation;

2) Turns off more often when running on battery power;

3) Under OS Windows (bootcamp) doesn't shutdown MacBook;

4) This is not a kernel panic failure (no crashes, no dumps), so may be this is the normal shutdown of the OS X.

5) In the logs there is no record of the reasons for the shutdown (or "-128 unknown error" on older OS X version). As if nothing happens.

6) Can switch off when Mac sleeping.

7) Apple Service Diagnostic hardware tests (EFI, OS)  - all pass ok.

8) SMC and PRAM reset - doesn't solve.

9) Antivirus - no viruses - doesn't solve.

9) Only python script runtime executing in the terminal stop shutdowns of the MacBook Pro.

Before suddenly shutdown, for example:

Python script:

while True:

    sleep(0.00002)

What is the reason for this problem?

It is experienced by a lot of users, example:

Help! Updated to macOS 10.12.4, MBP randomly shuts off | MacRumors Forums

SOLVED: MacBook shuts down randomly with still battery charge left - MacBook Pro 15" Retina Display Mid 2012 - iFixit

and many other identical messages.

well if you are not an Apple Authorized Repair Specialist and you are in there reapplying thermal paste and messing with cooling I'd look at the possibility you have hosed that box trying to fix it.

AV Products for Mac have been found conclusively on these forums as causing problems but little else and since there are no OS X virus in the wild at this time their effectiveness is conjecture if that suddenly became a reality.

If your system can stay on long enough to remove the AV product then I'd start there.

If you experienced every few minutes unexpected unexplained reboots MacBook, which happening to me and my friends (which made them buy a new Macbook Pro), then you would believe in the viruses for the OS X and other supernatural causes.

AV was installed today.

The problems were observed before AV installation.

I repeat, installation of the clean OS X doesn't solve the problem.
