You're going to give Norton a bad review based on one day?
Yes. As you saw, my experience was really bad. I uninstalled Norton cause those 2 false positives it found were sites that i use a lot. So if i wanted to keep it, i'd have to face Norton blocking those pages all the time - as Norton doesn't offer any way to exclude those pages from the signatures.
All comments i did were based on experiences that can be evaluated in that time. For example, the installation process, the management of configs, and - surprisingly - finding 2 FP in 1 day.
BTW, i made clear that my experience is limited to that period.
"However, the extension installed on all browsers kept running in background by default."
??? That's a browser config when you install ANY extension, just disable it. Nothing related to Norton.
Actually it isn't. I meant it was running in background even after closing the browser. All those browser i mentioned were minimized for that bottom bar with norton, day, sound. etc... after closing the browsers. The only extensions i've ever saw with this behaviour were VPN extensions (meant to keep the VPN access 100% of time with the installed browser) and Norton extensions.
Other extensions like Kaspersky protection, Bitdefender TrafficLight, Htttps everywhere, ublock, etc, are only loaded when (and during) the browser is in use.
I don't like that too, but it's a common practice on the AV industry.
Unfortunately
I think you are overreacting, it gives the option on the page to CHOOSE what you want to install.
I think that a paid AV shouldn't even consider telling you to use their search engine "because it's safer". Its probably as safe as using google or any other. Maybe it will exclude some pishing pages from the query, but thats why you already have SmartScreen, SafeBrowsing and the Norton web defense itself (without mentioning MBGD, BTLS, etc). The only true reason they ask you to use their search engine is to make more profit with you, by tracking your web habits. So basically you are paying to use their service and to see them asking you to track your search - and send more information "anonymously -, so they can make more money with you. I don't think it's ethical, and i would not trust a company that tries to explore its users in every way they can find.
but what you said it's kind of non sense.
I don't think so. It certainly makes more sense than saying that all extension run in background by default
