Good Morning, I installed the newest version of ccleaner and when I ran the ccleaner, Windows defender utilities 18kb came up as did avg antivirus 8.0 utilities 51,051 kb. Should I let ccleaner delete these files??? Also, Windows explorer cache thumbnail 1028 kb. I am not computer savvy, but when it came up "utilities" I was afraid to delete them. Can someone please help with this?
Thank you.
