Are you saying hardended mode does not gives false positive? Your both statements are contradictory. If you set hardened mode then you are bound to get false positive. And you are not considering 360 TS for it's false positive.
You do not catch my point, probably or I did not descibe it well enough
with default settings (both programs) qihoo has more false positives than Avast. Thats for sure.
With hardened mode (moderate) enabled, I dont have come through any fp with the latest version of the program. With qihoo at defaults, I still encountered 2 fps the first day. But that may be a case and not a general rule. The reason I talked about hardened mode was to point out that it can offer good protection, the same or maybe better than qihoo.
Yes, I am a bit disturbed by the small delay Avast causes to Chrome launch time (whats good is that with the future experimental 64bit version things are ok), but Avast remains less buggy and more robust overall. Qihoo needs to get more mature. After a reboot, a message appeared saying 360 has crashed etc... This caused a very very very bad impression to me.
