Agree with your points you make, BUT BUT BUT you can delete KVRT files and restrict access once a scan is finished. Less risk for me=win.
One thing having a temp scan with temp files vs a Kaspersky rootkit permanently installed. Plus I would never run a KVRT scan on work files, just personal.
I have nothing against Russians or KS, in fact I admire their technical skill and protection but sadly geopolitics gets in the way of using their software.
