Every time I run CCleaner it finds and deletes everything except the same 30.2MB. I am running a plain windows 7 desktop.
Where or what does it say that the 30.3MB is?
I just run the program ... say it says there are 63MB to be erased .. I say OK .. it erases everything except 30.3 MB. I do not know what it is or how to find out what it is. This never happens on any of my other computers.
I think @hazelnut was after more detailed info.
like, instead of running CC, hit Analyse and see where the files to be moved are.
then run CC, after it has finished, it shows what was removed.
now you can compare the two and see where the leftovers are.
any chance you have both the only delete files older than 24 hours ticked?
Gotcha ... the left over files are .... Utilities - Avast! Anitivirus 31024kb - 1file
There you go, your antivirus doesn't want that file touched. I'd add it to your ccleaner excludes
