There is no adware in the avast software.
If you believe otherwise, you don't know what adware is.
By installing avast you agreed to the EULA.
avast doesn't have to ask or give a notification upfront.
Sure, it would be nice if they did but they don't have to.
I am not an expert in this field, nor a law expert. I do not know the techinical definition of this, and frankly I am too lazy to even look it up. I am a simple user. But I, and I believe a great deal of people, have a rough idea of what adware is.
And this softawre is for me, exactly that. I dont need it. I dont want it. I was not asked for permission. I was not notified. That for me is enough. You can write all you want, but even you know that I am right.
As for the EULA... well I have not read the EULA (who does it seriously with every software they install) but just to say a few things:
1) even if you have the legal right, that does not make it the moral right and just fyi (moral>> legal)
2) I do not know the law, but I do expect that even in the EULA you can not make everything you want legal. There are still consumer rights, such as the act of good faith etc, which do state that a product has to be fit for service, for example. An antivirus software that is itself installing, what I would group under adware, does at least for me, not fir its purpose.
3) and even if you are techinically right on your points, I dont even care. I very much have the right to state that this is BS and dislike it.
4) Now on this I am not 100% sure, I dont have any proof. But I do suspect that for example the price checker uses your search information to sell it to sites such as amazon etc. As, even if it does say so in the EULA, it contradicts its own advertisement of data protection.
Frankly I dont even know why I am arguing here.
