A late response, I know. So slap me on the fingers for it ;D But looking at the screenshot Bob posted earlier, I would say not needed if you have Avast, Spybot s&d, Ad-Aware and a good firewall. (router with hardware firewall is the best) Looks that it is not adding anything to the protection of your system(s) if you have the ones I just mentioned.

This is just my first impression and I have to look into this application before I can give more details or perhaps even change my mind about it. But at a first glance (is that how you say it in english?) this is what I think about it.

Wondering why they call it Qwik-Fix while they claim to protect/prevent things…
