You are wrong (again).
You disagree with me. Not the same thing. But recognizing the difference is clearly not your strong suit.
avast is doing that (and more).
That 'more' is what the user should have ultimate say over.
No line is crossed.
The user has chosen a av that is using this technique and agreed that it is used.
It is needed to detect and block new malware as fast as possible.
Initially only the hash of a file is send to avast for analyzes, not a file.
If it is done without explicit consent, a line is most definitely crossed. Avast has a habit of installing new features without asking, so what a user has agreed to at first install years ago is not the same as what Avast is doing now.
Privacy has nothing to do with it as no personal data whatsoever is being send/requested.
How can we verify this? Also: if a file is sent, it can certainly contain personal data, so your statement is false. Only checking locally ensures privacy. Even a hash identifies a local file to Avast.
If that is so, the OP should use a av that never connects to the net.
Good luck finding one
You're either deliberately being thick, or just asinine. Very typical Eddy. No help, just arguing for the sake of it. Just deal with the fact that different people want different things from their AV, and that you are not now nor will ever be deciding for people what they should or should not accept.
