[Huge quarantine file needs removing]

I ended up with a remote session, with a Kaspersky expert.  It turned out that the self-defence mechanism was seeing the file as a necessary one, not to be tampered with.  Turning off Self Defence, deleting the file, then turning Self Defence back on has solved the problem.

 

Grateful thanks to all who have tried to help me.  I hope this solution will help someone else.

Unfortunately, that gave me the same perms error.  I suddenly realized I have a (rather old) Knoppix disk.  The problem is that my DVD player is USB.   I managed to get to the boot menu eventually, but Windows boot is the only option, and it doesn’t seem possible from there to disable UEFI. <screams in frustration>

C:\WINDOWS\system32>rd /s /q C:\ProgramData\Kaspersky Lab\AVP21.3\QB

Any more ideas?  I really don’t want to have to re-install Windows.

Despite all Google’s attempt to help, I’m still not managing to enter Safe Mode.  After the Troubleshooting selection it lists a number of tasks, saying that to do those I must press Restart.  When I do I seem to get a normal restart.  The only difference I can see is that I’ve slightly more free space on C: than I had, which may mean drivers not loading?  I’m struggling.

Whatever - I still get the same permissions message.

The laptop is an Acer Aspire 7.

Hmm - Pause enabled until next re-start, but I’m still getting the same permissions message - attached.

 

Thanks for answering

I have a 126 GB klq file in C:\ProgramData\Kaspersky Lab\AVP21.3\QB.  From the main A=KAV interface there is no listed quarantine backup file.  File Manager sees the file, but resists all my efforts to delete it.  I am an administrator on the laptop, but am told I do not have the relevant permissions.  How can I get rid of this file?  It takes up half of my drive space.
