Sophos locks my hard drive, I cannot format it.

Hi Rico,

Thank you for reaching us. When you mentioned that our endpoints lock your hard drive, may I know if you’re using Sophos device encryption to it? And what was this detection that you've shared? 

Hello,

no, hard drives were never encrypted with any tools.
I wanted to erase my hard drive.
I deleted the data.
I wanted to format the hard drive on it.
Then the error message came up:
An attack on a vulnerability in an application was prevented
WipeGuard
C: \ Windows \ System32 \ dllhost.exe

If I now want to format or rename the hard drive, it appears that a user has opened a file or access is denied.

Then I wanted to remove Sophos so that I could get back to my hard drive.
That also fails, there is an error message here too.
Sophos Autoupdate cannot be stopped.
All manual attempts failed.

The problems started with Sophos and I can't get it removed even in Windows Safe Mode.
The reinstallation does not work either, even here there is an error message.

You may try removing the Sophos endpoint first, but before that, you need to manually set the registry key for auto-update back to zero to stop Sophos auto-update from running. 
Go to this registry path "hklm\software\wownode32\sophos\autoupdate\updatestatus > is updating change to 0"  and change the value of "is updating" to Zero,
Then remove Sophos Using Sophos ZAP tool refer to this knowledge base article. Once done, you may proceed with formatting your hard disk and let us know the status. 

hklm \ software \ wownode32 \ sophos \ autoupdate \ updatestatus does not exist

Apparently I was able to remove Sophos through SophosZap.exe. Links are at least still available, but a call no longer works.

If I reinstall Shopos, the same problem occurs again, I can no longer uninstall Sophos.

I have to go through the same steps again.
Now that's not very nice.
