This software is malware. It must be removed from the Chrome store.
It's installing without permission, presumably as bloatware in other software, or more maliciously through phishing links.
It's deeply suspicious. At best, it is advertising an unneeded service (I noticed the infection when this extension I did not install had the sheer stupid nerve to show a pop-up notification trying to link me to their website, where it's asking me to create an account). It was very obviously suspicious as I had only one extension installed on this machine, ublock, and this is a clean windows install from less than a year ago on a work machine.
A side note, Google. This is why we use ublock and other adblockers, because you, and other advertising companies, have a near reckless disregard for user safety and ads are often vectors for scriptjacking and phishing attacks. If your ads were not a literal threat, people would not go out of the way to remove them. You can keep trying to shut down necessary security software like adblockers through dodgy acts on your storefront (but somehow let these chancers keep their malware up), and all you'll do is force people to choose a different browser, and drive them out of your ecosystem. Your software development staff know as well as your users do that adblock is a necessary security measure on the internet, it always has been, and always will be.
This software literally looks like one of the old school fake antivirus malware scams that tries to make you download more malicious software and give it access.
The clowns who made this will respond to this apologetically, like they have to all of the legitimate reviews. I suspect most of these reviews are fake, because they're either blank, or just say "love it!" lol. Nobody "loves" their security software, it either works or it doesn't. Saying you "love it" would be like saying you "love" the coolant in your car. You don't care about the variety, you care if it works or not, if it does the one thing it needs to do, and if you're desperate, you'll put water in it to limp it somewhere. I don't care how nice you talk to me, I don't care how politely you apologise for invading my privacy without consent: you cannot win back a user's favour when you violated their consent and acted in bad faith. I'd happily see you gaoled and restricted from working in software for life.
I don't "love it". In fact, I hate it. No legitimate security software would conduct itself in this way, you need to trust this sort of software implicitly, and the way that this software operates destroys any trust at all. The way Reasonlabs have conducted themselves shows that all of their security certificates should be revoked, and Chrome should notify users that the site is suspicious like any other suspected phishing site.
Avoid Reasonlabs like the plague. They are untrustworthy, and conduct themselves like scammers, black hats and bad actors.
I would recommend to anyone who has stumbled on this review (probably because they infected your browser too) to immediately remove the software and report it to google, at the moment it is listed as featured. I would also recommend flagging the obvious spam positive reviews.
To confirm, this software is definitely malware. After removing it, it ran a command line prompt to attempt to re add it to chrome. This is not the way any legitimate software behaves. I was forced to go through the registry and remove all references to it, so that it would not keep trying to reinstall itself. This is not how a chrome extension is meant to function at all, and almost certainly violates the terms of the chrome web store. I suspect this is a data harvesting operation.

Extension safety
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk
impact extension cannot do much harms, whereas a high risk impact extension can do a lot of
damage like stealing your password, bypassing your security settings, and accessing your
personal data. High risk impact extensions are not necessarily malicious. However, if they
do turn malicious, they can be very harmful.
Online Security requires a lot of sensitive permissions. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Chrome extension may turn malicious.
This is determined by the publisher and the Chrome extension reputation on
Chrome Web Store, the amount of time the Chrome extension has been
around, and other signals about the
Chrome extension. Our algorithms are not perfect, and are subject to change
as we discover new ways to detect malicious extensions. We recommend that you always
exercise caution when installing a Chrome extension.
Online Security has earned a fairly good reputation and likely can be trusted.
