Norton 2010 Full Idle scan question ??

Hey the Norton community!!

 

Today my Norton did an idle scan full. Evrything was good untill a big fat red cross came out saying norton found threads and fixed them! The threads were cookies. My qeustion do cookies always be found by Idle scan and should I worrie when I see my Norton sighn with red cross next to it? even those it says it fixed it?

 

 

Thanks alot Norton ! hit me back peepz

 

One love !
