Errors during paging operation after Bitdefender update

On 21-Dec-17 Bitdefender 2015 required to restart my computer because of a major update.

Since then, at every reboot, I get a series of System Warnings (ID 51) saying "An error was detected on device \Device\Harddisk0\DR0 during a paging operation."

These are probably related to system files trufos and avc3, which seem to be Bitdefender system files.

Something to worry about?

Any solution to this?
