Greetings,

No, quarantining the detections will not corrupt Chrome.  It is likely that some software you installed came with a bundled PUP  (Potentially Unwanted Program) that altered your settings in Chrome, so Malwarebytes will restore it back to defaults if you allow it to quarantine the detections.

Once that's done, if the detections return then it could be the result of the sync feature in Chrome.  You can correct this by following the instructions in this topic.

Please let us know if there are any further issues or if there is anything else we might assist you with.

Thanks

Hello, first i would like to ask if MB detecting malware,adware,phishing or etc from google chrome does MB will labeled them in threat type category as pup.optional.defaultsearch or not ?

[exile360]

Malwarebytes will label each as determined by the Malwarebytes Research team, so anything overtly malicious will most likely be tagged as actual malware.  Anything detected as PUP would be things like adware and the like which aren't necessarily harmful, but could be undesirable, annoying or unwanted.

You can learn more about what Malwarebytes classifies as PUP and why at the following links:
