SHIELDS OFF/ON

Each time i start the pc a warning says that Ransomware shield and Behaviour mode is off , i turn then on but next startup they are off !!
Also when selecting a Full Virus Scan it takes 2 secs ,then says no problems found,surely its not that quick now it used to take  some time to do it .
