removing avast free

Hi I have removed Avast free from my computer but the folder is still in program files with big number folders that I can not delete as it says the folders are not empty but I can not see any think in them how can I remove the folders thanks

Follow instructions: https://www.avast.com/uninstall-utility (Run this tool for all prior installed Avast versions…!!)

thanks for that Asyn tried that but no look still there after i ran it and i still cannot delete the files

Boot into safe mode and remove it manually.

tried that it say’s the folder’s are not empty but you can not see any thing in them !

Are you sure this is what you did ??? ???
