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
