Thanks for all the help so far. Maybe I can provide some more information, even if we don't know exactly what the problem is and whether it's caused by CCleaner at all. I have logged the cleaning process using the Process Monitor App. All recently used exe files were emptied again while doing a Custom Clean. The changes can be quickly found via Windows Search (see screenshot modified_exe_files.png). As an example, I picked the DropboxThumbnailGenerator.exe file from the Process Monitor log to track the changes. This resulted in the following image (see screenshot proc_mon.png). The process was like this: - 20:24: CCleaner (V. 6.02.9938 64bit) was loaded and I started an analysis (Analyze button) - 20:25: I started the Custom Clean - Between 20:30 and 20:34 the temporary files were processed and deleted by CCleaner - 20:30: Finally, the DropboxThumbnailGenerator.exe file has been modified - 20:34: The cleaning process finished According to the Process Monitor log, the original DropboxThumbnailGenerator.exe file appears to have been emptied via the System Prozess (ID: 4) immediately before CCleaner handled the temporary DropboxThumbnailGenerator.exe file (sentry_temp). I selected 3 erase cycles which can be seen from the log. Hope this is helpful.

Hello everyone The problems persist. I uninstalled and freshly installed CCleaner (version 6.02.9938). Then I did a custom clean. The result was that again many recently executed EXE files were modified (even the CCleaner.exe ). The files were changed when the program was deleting temporary files. Again, these EXE files were overwritten with all-spaces. I was able to recover all the files because I had a fresh backup of my computer. I emailed support as requested by Andrei and I'm excited to see how it goes (probably after the weekend). Best regards Ron

Hi all I'm experiencing the same issues. After a Custom Clean with CCleaner, some EXE files are corrupted. The files are still there, but the content has been overwritten with spaces. The sizes of the files seems to be the original file sizes of the specific exe file. It affects many major applications: Excel/Word, VLC Player, Defraggler, ... The list is long. I have to reinstall every single application. My system: Windows 10 with all updates, Ccleaner latest version (auto-updates). No malware, no virus. DISM and SFC don't help. The SSD is fully functional, no errors there. Maybe we can find an explanation for that. Greetings Ron
