Hello,
thanks for your reply, but I regret to inform you there was no such option.
Not only that, but to be sure I didn't overlook it, I actually went through the installers two more times just to be 100% sure.
I just downloaded a fresh copy from Piriform to test, the pic below is what I see as the first screen that opens after running the exe file, clearly displayed is a preticked Avast install option.
Whilst it may well be there, there really is no way that option should be pre-checked by default, not for what is such a major program, not some little function. When you consider the size of CCleaner (approx 16MB), Vs avast at aprox 256MB for the off-line installation.
Now I know that they aren't downloading the off-line installation file, but it is even worse when compared against the installed size of avast.
Even more, something as critical as an AV being installed, shouldn't be an opt-in option. You are effectively installing Avast when there would be another AV present, even if this was windows defender.
