In addition, the use, in my opinion, absolutely simple. The interface is clean. After the initial installation let and perform a full scan of their software. That takes a bit, but is relative to other protection systems neither slow nor fast.
Updates run silently in the background here whatsoever. Since there are only positive to report. As I said, if you want to have a really good software for multiple devices, then they are incorporated, among other things well served. That the protection at this price also runs 2 years, is already unquestionably good.
