Inadequate behavior of Avast Premium Security

Avast has been killing many programs in the last few days.
The version of the program is on the picture.
Error: 0x00000003, 0x0000005 and others appear when launching programs. It even killed its own Avast Cleanup program. Can you please tell me what’s going on?

Hi,

Can you provide us with screenshots of Avast detection messages or any error messages, please?
