    Wait for the app to analyze what files can be removed.
  4. 4
    Select what files from the list you want removed from your computer. If you want to save even more space, press Clean up system files and the app will reanalyze your device and give you the option to delete more files.
    • There is a description box at the bottom of the app that will tell you about the file you have selected right above.
    • Sort through the list carefully and uncheck what you want to keep (e.g. the Recycle Bin files if it contains files that you're not sure you want to delete yet).
  5. 5
    Click or tap OK to continue.
  6. 6
    Confirm the file deletion by pressing Delete Files from the warning prompt.
  7. 7
    Wait for the files to be cleaned up. The time that the cleanup process takes will vary, but it'll probably take longer if these files have built up in your system.
    • After the cleanup finishes, the Disk Cleanup window will automatically close.

    Try running a virus scan on it using your antivirus, if you don't currently have one installed. Try the free version of Malwarebytes. If that doesn't work, it is suggested that you try recovering your important files (after scanning them) and formatting the drive.

    If you are talking about isopropyl alcohol, no. Your best bet for getting rid of a Trojan virus is running a virus software scan such as Norton, MS Security Essentials or McAfee virus programs.
