It may be detecting those domains (or simply the fact that the hosts file has changed) as a potential malicious change. Truth be told, the hosts file is not meant to block domains and is a common misconception/misuse of the hosts file. It's main intent is to help direct a (few) domains to new IP addresses, such as in the case that DNS has not propagated with updates. If you'd like to learn more about it, you can read about Blocking Malware and Advertisements Safely.

Still coming from toolslib though.

@fr33tux Only when threats are detected. I'll keep an eye on it to see if it's still doing it, too.

There are no log files available.

Additionally, the close button as seen in your attached screenshot does not actually let you close that dialogue box.

Under Settings > Basic Repair Options... All settings are set to On. Video example of what happens:

@Elisabeth please reread my post. I'm sorry but your response sounds like a canned response and that my message was not read. Specifically, reread this segment quoted below: To reiterate, this means... When I click Clean & Reboot Later AdwCleaner still forces a reboot as soon as cleaning is complete. As such, it is not honouring where I would control when the reboot happens. When I click the red X at the top of the options for cleaning, it still forces a reboot as soon as cleaning is complete. Despite that the X was clicked to signify not performing and cleaning or rebooting at all. The original post is stating the expected results, what actually happens, and the steps to reproduce this bug. Thanks.

This may be because of a setting that gets enabled, such as under Settings > Basic Repair Actions. I've noticed this consistently. Whether you click Clean & Reboot Later or the red X at the top right, it will still clean and reboot. There's also a minor display bug for the &.

Just to add a bit of humour to this. Looks like Google needs to step it up a notch! https://imgur.com/VWoExLX https://i.imgur.com/VWoExLX.mp4

The anti-spam/captcha is the key issue, not really that of IPS. As such, it's actually Google's fault for such a poorly implemented method of stopping bots. It's annoying for anyone and everyone. They were supposed to come out with one where you never had to click anything, called Invisible Recaptcha. I now see they're working on a version 3, which sounds promising. No one wants to be harassed by unnecessary clicks and puzzles.

To block ads and more, I'd recommend uBlock Origin. It goes above and beyond what AdBlock Plus does.

The site never clearly describes what the software is doing or how it's doing it. "PCs are slow by design" - seriously? You are seriously trying to market your software by saying that a PC is slow by design? That is the most absurd thing I've read all day. PC "optimizers" (game "boosters", RAM optimizers/cleaners, register optimizers/cleaners, etc.) do more harm than good to any computer system. They advertise that they can do all of these wondrous things that will make your computer run so much better, faster, and be more responsive. When in fact they stop services that are running for a good reason (leave services alone!), try to "defrag" your RAM, and many other unnecessary things that degrade your computers performance instead of optimizing it. As @Zynthesist has said and I fully agree with, this is indeed a Potentially Unwanted Program (PUP). I would immediately uninstall this "Fast!" software from any computer I'd work on.

Try clearing your cache, etc. Also try In Private browsing to see if the problem happens there too.
