Got an example? I haven't heard anything about this and I'm genuinely curious.

There has been critics on the quietly updating of root certs by Microsoft.

This is what I tell my family and friends. Whenever I help someone upgrade to Windows 10, or work on their computer, I tell them to just use Microsoft Defender.

I've also read various reports of security problems with AV software, so I'm not comfortable recommending anything third-party.

Defender + uBlock is a pretty simple and effective combo.

You can manage pre-installed root certificates manually in Windows. As far as I've seen, there was nothing sinister in default Windows root CA list.

Microsoft just silently adds back root certs when you delete them (if it is trusted by microsoft). Or at least it did in winxp by default.

> In the name of "security", this undermines the very purpose of what HTTPS is about, knowingly endangering their users. It doesn't have to be insecure. If the software that does the MITM checks the certificates correctly, I don't see how it would be worse than letting the browser handle it. Not that I'd ever use an antivirus, of course.

It actually is worse. The problem comes "what does the interception do when it encounters an invalid certificate"? So for example a self-signed cert. does it a) create a "valid" cert itself, hiding the error from the user? This is obviously dangerous b) create an "invalid" self-signed cert. This is messy as a user will then see a self-signed cert from the A-V vendor, which they may be more or less inclined to trust c…

It can simply stop the connection and show the user, under the normal certificate, a message telling him there's a problem with the cert.

That's hardly relevant for the average computer user. By default, root certs are updated automatically.

Are you in any way related to MS or is your memory just very short?

I got for free Norton Security with my new Dell laptop. On installing I was unable to enable windows defender or firewall. Norton takes over the security by default.

I contacted Symantec and had to uninstall Norton Security and install Norton Antivirus for the windows firewall to be activated.

What's more, as third party antivirus software becomes increasingly irrelevant, many of these companies resort to harmful and even actively malicious tactics to stay in business. On the more benign end, you see an increase in 'safe web browsing' and such tools that parse javascript while browsing and somehow attempt to make it.. safer, I guess. My main experience with these things is when they randomly decide to bloc…

> I should say here that I fully expect someone reading this has managed to uninstall an AVG toolbar with no issues. They have multiple different auxiliary tools to their antivirus, and I'm not sure specifically which one(s) caused me trouble personally. I can say this: I never had a problem with uninstalling a browser toolbar, or restoring the default search engine in the browser. What I always have problems with, i…

Ya, IIRC it wasn't specifically the AVG toolbar, but some other thing in integrated into the browser. It refused to uninstall, and then even when I downloaded and ran the super-secret installer from their site, it replaced itself on the next restart. Extremely frustrating.

No, I don't think so and if it does, please tell me which browser does it so I can keep away from it, because that defeats the purpose of TLS. Either way, Bitdefender installs their own root certificate and generates their own for google.com. I've got proof if you want.

Chrome, Firefox. Probably more. https://developer.mozilla.org/en-US/docs/Mozilla/Projects/NS...

That's for the Wireshark debugging use case.
