It works very well ... I like it no telling how many times they have saved my computer from crash and burn and it also alerts you of suspicious sites ... love it and it is reasonably priced.

Have never given PC security much thought. Usually just download a free one! The last couple of years the free ones have annoyed me so much with their constant advertisements for themselves etc, that I removed them from my computer.
It was great to discover Guardio, It has been a relief having it with so much going on in the world and so many nasty people scamming innocent people. It's great when I think I want to click on a site and a Guardio message come up saying they believe it is a dangerous site so I don't go there.
