Le site f-secure.com est-il sûr ?

Never again will I download this. First, upon downloading, it restarted my computer without asking or warning me. Then, after trying to just open the program (it took around five minutes) I tried updating my virus definitions. After waiting a few minutes as it was still at a very low percentage, I opened Firefox. The updates suddenly canceled, the program restarted itself, and my computer nearly froze. After a bunch of pop-ups came up asking me if I want to allow Firefox and other programs running, window after window kept showing up saying VNC is spyware. The windows kept coming and coming, and so I tried uninstalling the product. After a ten minute uninstall, it was finally gone. This is no antivirus-it is the virus.
