Can't delete file in hidden folder even after changing owner

I have removed such files using Ubuntu, downloaded as an ISO and installed
on a bootable thumb drive, using Unetbootin. Such a little item is very
handy and with a decent Thumb drive, is quite impressive.

FWIW, MSE found and removed a trojan installed along with Unlocker on one of
my machines. Moreover Unlocker does not always work, and when it does, I
wonder if it is safe..
