I have Opera Next or Beta .
This software didn’t detect Opera.
On my Windows 7 Opera is installed on drive C: & in Program Files .
It is my default browser so it should have been detected .
Also FireFox portable wasn’t detected & I expected that .
The only detected browser was IE which I never use unless some web site requires it .
So Fast Browser Cleaner is of no use to me.
If someone knows the fix then I will leave it installed .
Otherwise I will uninstall it.
