Found this weird issue the other day.

The normal location for ClamWin's quarantine folder is 'C:\ProgramData\.clamwin\quarantine\. It looks like your folder is originally in C:\Users\All Users\.clamwin\quarantine\. ClamWin found some infected quarantined files there, so it put them in its normal quarantine folder.

What kind of system do you have? Maybe you had an older Windows OS and recently upgraded it to something newer. If it is newer than Windows XP, I suggest that you just delete the quarantine folder in C:\Users\All Users\.clamwin\quarantine\ and leave the 'C:\ProgramData\.clamwin\quarantine\ normal folder.

Thanks for using ClamWin!
