Pop up window at win 10 boot annoyance ?

Every time I boot up my win 10 a popup said do you want this program to modify (something)?? and of course it's CCleaner so here I am asking what to do to get ride of this??

Try turning off Ccleaner monitoring

Good hazelnut, i'll try that and post back.

Thanks!!

System monitoring didn't change anything.

So monitoring (and system montoring) is definitely turned off ?

How about in CCleaner settings... is ''run CCleaner when computer starts' ticked or unticked ?

would attaching a screen shot of your pop-up message explain things better to us?
