Hello, Yesterday I Download the new version of CCleaner v1.23.160 (I use Win XP-Home Version) and I have the problem that the index.dat file in temp.internet files after running CCleaner is 2.2MB big (with the old version of CCleaner the index.dat file was delete after running CCleaner). After a restart the computer the index.dat is delete but running CCleaner again it's 2.2MB big. What is the Problem? Please excuse my bad english and thank you very much fore answering. Best regards
