Thru an Avast configuration path I can be driven to a cookie list in my PC. So I checked them before opening my CCleaner free version for an analysis. In fact, CCleaner detected about 3,000 cookies to be cleaned and I clicked for cleaning them. CCleaner reported that was done. I returned to Avast path as said and all the cookies were still there. After all, is CCleaner 5.46 cleaning cookies or not? (Sorry for poor English)
