Ratings and Reviews

OS Cleaner Master


What use is it. I have used it a number of times and it does not finish. Each time I open it it asks to ‘Scan” after it scans it asks to clean, I click ‘Clean’, it says No Problems. BUT the files are still theree. No matter how many times I Scan & Clean ,and the program says NO PROBLEMS, I close and reopen all files are still there, USELESS.

Developer Response

Please update to the new version. Thanks
