Okay. What to do here?
You can remove Google Chrome browser if you want, as it is seldom necessary. Most websites work with any major browser, and Chrome is not necessary for accessing any of the major Google services. It’ll also eliminate that browser extension app that the add-on MalwareBytes is reporting as potentially sketchy.
Here, MalwareBytes is seemingly pointing at a Chrome extension. To remove the browser extension from within Chrome: https://support.google.com/chromebook/answer/2589434?hl=en (or ignore it, as the extension has apparently already been disabled).
If you want to look for the Chrome browser extension file manually, you’ll need to look at the rest of the path MalwareBytes is (not) showing in that message. The missing part of the path specification is shown below circled in red. Tap on the area in green, and see if it’ll show the whole path to the file.

What about add-on system tools more generally?
I’m not sure whether any of this whole sequence is but reacting to noise. Add-on security apps and add-on anti-malware and other such apps all tend to be noisy (noise: “look at meeeeeeee!!!”, a form of self advertising), and for not much benefit. Not past what the built-in anti-malware provides. Noise: the app that reported this has already told you that you don't need to do anything.
Add-on cleaner apps, add-on optimizer apps, add-on anti-malware apps, add-on “coffee shop” VPN apps, and other similar add-ons all tend to have poor reputations around here. And they’re too often noisy, and too many of the apps can be collecting data or subscriptions for questionable benefits. One of the major add-on security apps was erroneously reporting a macOS component as malware for months, and various others have tried deleting parts of macOS itself. Which would be bad. macOS does pretty well all by itself, and does well at protecting itself, and without added help.
As for Google and Google apps more generally, Google is an immense advertising and tracking organization, with sidelines in web searching and apps that are themselves data-acquisitive. The common Google apps can get immensely busy doing who-knows-what too, and the apps have a longstanding reputation for being resource-intensive. And it is unusual for a mainline website to require specifically Chrome.
Safari works fine as a web browser.
If you do need a Chrome-based browser for some weird or low-budget or data-acquisitive website, Vivaldi uses the same foundation as Chrome, but lacks the Google tracking bits.
What security features should you be looking at?
Weak or compromised or re-used passwords, no two-factor authentication, inadequate or no backups, unfamiliarity with phishing and social engineering schemes, and some other topics.
We’re not getting viruses, we’re getting phished, and our compromised and particularly re-used passwords are getting tried everywhere.
