Windows security page blank, Win updates not working...

[Jojo]

As stated in title.

I know the cause. Hitman found and removed winlogui & winsmserv from System 32 successfully, they haven't reappeared.

I did try a couple online solutions(https://www.partitionwizard.com/partitionmagic/windows-defender-blank-screen.html):

1)Restart Windows Security center service in services.msc...Restart option was greyed out.

2) sfc /scannow command...said it repaired corrupt files, but no perceptible difference

Also, I do have three Acronis backups of this drive:

A) Older barebones image after Win 7m pro upgrade to 10 pro. Integrity seems good. Recovered successfully from it.

B) Yesterday, no signs of the virus. I did have to Scan and repair with CHKDSK after I made it though, so integrity is a question mark.

C) Yesterday, after correcting with CHKDSK...has virus files.

Ideally, I'd like to repair the OS and the make an updated Acronis backup. Also, I do have a separate hard drive with Win 10 Pro installed. It's near pristine. Unfortunately, the drive is over 5 years old, so I don't trust it as a main drive. The drive in need of help is one month old. I bought it special to upgrade to Win 10(4 TB WD Blue).

Any ideas on how to best proceed?
