idle time optomizer

ok so norton is really pushing my patience at the mo, for some reason it starts the idle time optomizer, even though my comp isnt idle, i keep canceling it out but 10 secs later it starts again, ive even turned it of, but still it starts up, the trouble is its lagging my laptop down, my mom as the same problem, background task should only happen when is idle, my idle time is 30 mins,

 

has anyone else experienced this or got a fix for it please

 

thanks
