dumps +crashes while playing with malware on external drive

[Helios_07]

Real PC:

Windows 10 64-bit Version 2004

Build 19041.264

KTS 21.1.10.361

um:breakpoint_avrf_80000003_qscan.kdl.f0fdc2cdf0d1b6a10fda4fdbc3bec9ca_0!unknown

um:application_fault_avrf_edef9f2d_instrumental_services.dll!unknown

um:null_class_ptr_write_avrf_c0000005_ipm_service.dll!ekagetobjectfactory

Reproduction steps:

i loaded up a couple testmalware files turned programmcontroll an file-av back on scaned the folder with the malware (on my external harddrive).

KTS wanted to run a disinfect scan i chose run scan without reboot.

The disinfect block that blocks starting files was annoying so i turned off my external harddrive where the testmalware is located.

Thats when the dumps and crashes started. 

Actual result:

KTS started to create dumps then crashed after turning off the external harddrive with the malware

Expected Result:

scan gets canceled due to missing file location.

Hi Dmitriy,

i only managed to reproduce the breakpoint dumps.

1.I unpacked the testmalware on my external harddrive

2. i ran a custom scan of the folder with the testmalware

3. while KTS is processing the malware i turned off my external harddrive

4. KTS immediately created the breakpoint dump once the again and crashed.

During that reproduction test i discovered another dump and had a klif caused Bluescreen, both i will report separately. I will keep looking into it, my reproduction was different so it made me curious.
