Well e.g. they don't spam you with ads for their other products. They like to say that your PC is slow and show you their nice tools that should fix it (although I know avg does that, not sure if avast too, but they're supposed to be the same thing now). People tend to freak out if they see something like this popping out of taskbar. Eset doesn't do any of this and keeps quiet unless there is a problem. Also don't add snake oil parts to their products like registry cleaners and install extensions. The most obtrusive thing they do is probably MITM TLS connections which I don't agree with but at least kinda understand. As for the data monetization, you can compare privacy policy of those two companies https://help.eset.com/eav/12/en-US/privacy_policy.html https://help.eset.com/eav/12/en-US/privacy_policy.html vs https://www.avast.com/products-policy https://www.avast.com/products-policy . They speak for themselves.
