Hi
LOP can be difficult to remove beacuse of randomly created folders and
files. LOP or c2lop is the sponsor. I don´t believe that WD manage to
complete remove a LOP infest.
But this only occurs if you installed it WITH the sponsor.
If you installed WITH the sponsor it´s better to install again and then
directly uninstall.
But latest Messenger Plus is buggy. (a pest IMHO)
So after uninstall, scan with WD.
It could also be a good advice to run A-squared as extra check.
