How do I disable auto removal of low-threats?

Hi,

 

I just received a popup with a list of low threads (adware stuff) and after I elected to "fix" them all (i.e., NIS 2013 removed them), another popup occurred with the option stating something like "Automatically remove low threat items".

 

I accidentally hit OK but that's now what I wanted.  So how do I re-enable the setting so that it will continue to prompt me instead of automatically fixing?

 

Thanks!
