I don't think the question about Popup Killer has anything to do with this cdrsoft.cc (I hope so) because I don't mind 1-2 pops and especially no porn like cdrsoft does. But some sites they pop like crazy and they send you to nowhere, and you may end up to End Task or even reboot the system to stop them.
I do have several popup killer installed on my system *but* only load it when I run into a site with 10-20 pops, and only launch the Ad-Muncher (Ass Muncher) if they contains heavy porn (like FOSI I won't mind much because not so dirty and I can scroll the window up/down to hide them from my grand kids when they in the same room).
I even click the banner if the site is worth to support. Anyway, I don't have any problem with 1-2 pops from this cdrsoft.cc, and I think it has only 2 pops (?).
