You can't take ownership on a folder which can have malware or viruse
that have link to the registry,
And if there is malware.. msconfig or task manager can't see th
files.. correct me if i'm wrong!
I think the fact that the files had been copied from another pc can b
that it contains virus or malware.. but the secuirty option can still b
modified if you go on "properties" > security tab.. ofcourse if you ar
using the profile setup with administrative rights.
Or other option is to open the folder and delete the files one by on
and see which one is refusing to delete.. send us the details of th
file..
