But anyway, file with virus (for demo https://support.kaspersky.ru/common/diagnostics/7399) was removed http://take.ms/r27pd

Why don't work excluding? Could you help me, please?

I found that excluding didn't work with LVM partition. I've got error avast-fss: Unexpected AV SCAN response code (451)! in syslog
