Just as a rebuttal, I'd like to mention that it is because Avast does not have such a bypass feature, many of Avast's users are kept safe. (Probably from themselves.)
I feel the need to point out, that I suggest that such a feature be an optional that was disabled by default. You would need to manually enable it via the settings if you wanted the ignore option. I'm sure that average user, for which this option could lead to their system becoming infected, would not enable this option. Most likely, they just run Avast with the default settings, and never even look at configuration options.
Putting the decision of what's safe and what's not directly in the hands of the experts at Avast is the right thing to do.
Perhaps for the majority of users, but most definitely not for people such as myself. If Avast detects something I want to use, then I'll let Avast quarantine it, and then restore it and add it to the list of exclusions, or disable Avast's shields while I install it.
It is still the right decision to keep the customer safe.
It's not the right decision for all users. Maybe it is for the majority of users, maybe even for 99% of users, but not everyone. With my idea, the average user would be protected just as before, only a minority of power users would manually enable the ignore function, and it would keep everyone happy.
As an Avast user since 2003, I've seen both false positives and brand new viruses blocked by Avast. The false positives have always been rectified
in a reasonable time frame. The blockages of brand new infections of all types have kept my system well protected.
I first used Avast in the mid nineties, when there was both a DOS and Windows 3 app. But, I have used plenty of other antiviruses as well as Avast since then. Not only do I have 25 years of experience in PC virus removal, I know how to avoid getting infected. The only time I ever get infected is when I run an infected file I've downloaded, which I do from time to time. If I was a little bit more careful about what I let run on my computers, I would never get infected. I don't need antivirus software to tell me if a file is safe or not, I'm quite capable of doing that myself.
