It can happen sure.

Report them as false positives via my.kaspersky.com

Warning is correct. The certificate is not correctly installed. Not a Kaspersky issue but it did warn you about it. Please use a third party tool like https://www.digicert.com/help/ to check for yourself. Common Name = marujosbarbearia.com.br Subject Alternative Names = marujosbarbearia.com.br, www.marujosbarbearia.com.br Certificate does not match name lucasselbach.com.br

Post the name of the domain it complains about.

Check yourself via https://www.digicert.com/help/ or something similar. Those domains do not have a correct certificate installed period. Only a site webmaster can fix this. Nothing to do with KIS (Its actually alerting you properly).

If you do remove Admin rights form her user account she would not be able to install programs. Also in KIS there is a Trusted Programs mode, where you create a trusted snapshot of all allowed programs. https://support.kaspersky.com/13636

Please post the alerts that you are getting. Please note that default install should not be as annoying. You have probably customized something.

Well, its always good to have options. The choice to use them or not remains totally up to you!

I would only worry about this on a laptop and if you frequently connect to random access points and do financial transactions at the same time. In most cases keeping your computer up-to-date with the latest software and security patches would be sufficient for most users. Most of the time do not click on random links if you are not expecting it. Even if it does look like it should be clicked, mouse over it and see where it leads first. As most malware comes from clicking on those links and from unpatched software and OS vulnerabilities. So keep with your Windows Updates as well.

Whats in Device Manager for this particular device? It should have a log. Can you also collect some logs from your computer and post them here for us https://www.getsysteminfo.com

I am going to take a guess since its powered HotSpot shield you should get a warning of some sorts (again the exact integration that KL did is not known to me): https://support.hotspotshield.com/hc/en-us/articles/202439074-Does-Hotspot-Shield-have-data-bandwidth-usage-limit- In regards to the web page calculator you can get a rough estimate by reading this article: https://www.whoishostingthis.com/blog/2010/04/14/bandwidth-needed/ Let me know if that helps out!

That is just for VPN traffic. I am guessing your usage details will vary depending on how large the webpages you are browsing really are.

Only the released versions are supported by KIS. Any compatibility issues will be addressed post release via an Updater mechanism

Why? Because the number of malware is growing by leaps and bounds. Every large vendor: Apple, Microsoft, ESET makes mistakes from time to time. KL had invested a lot of research and development into minimizing those false positives (https://www.kaspersky.com/about/press-releases/2015_kaspersky-lab-patents-automated-false-positive-testing-technology-based-on-machine-learning-algorithms) You can report it via my.kaspersky.com to get a preferred queuing sequence. Switching vendors is a big hasty. Also this is a user forum, so your best bet is submitting the reports directly as indicated.

In auto mode its not possible. Thats why it had been suggested to contact KL Support and let them know about it.
