I've got a school lab with Ubuntu 18. On some computers, when Chrome is open I'm getting popups saying things like "local weather" or "Sandra transferred $99,999.00 PayPal" and the like.

chrome://extensions is blank

I need to a) remove the malware / extension and b) somehow lock down the ability to modify Chrome ?

Thanks ...

There are several extensions for Chrome that block popups. Poper Blocker popup blocker for Chrome is one of them. Also refer to How to prevent users from installing extensions in Google Chrome without admin privilege?.


My favorite is Malwarebytes Browser Guard extension for Firefox and Chrome. It keeps an eye on popups, ads, trackers, malware, scams and PUPs.


Turns out the popups were Chrome notification popups. Removing some websites from allowed popup sites fixed the problem.
