Of note: This also affects Asus Suite 2 as well. My machine is older and I have to use V2 to control the motherboard fan. The problem arose today when I turned on my PC. The Kaspersky database was from yesterday.
The problem is slightly different in that Kaspersky outright prevents V2 from running; there is no error message. I was greeted to the screeching of the motherboard fan spinning up and down. Even with expemptions in place it still won't run, nor will it allow me to re-run the Asus installation program.
After reading the thread on V3 I updated the database to current, but the problem still persists.
I've completely uninstalled Kaspersky and the Asus Suite runs fine again. It's a tough call: Do I rely on Microsoft Defender or do I wear noise cancelling headphones to be able to use my PC?
Windows 10 64bit, Kaspersky Internet Security.
