Malwarebytes detected 13 PUPs in Google Chrome


Recommended Posts

Hello guys, I ran a Malwarebytes scan then I got 13 PUPs flag in AppData\Local\Google\Chrome\User Data\Default\Sync Data\LevelDB. I already quarantined and removed the files and folders.
I use the following extensions in Chrome: NoScript, DarkReader, Live Server Web extension, uBlock Origin, Decentraleyes, Disconnect,  Application launcher for drive, Google Translate, Google Docs Offline, Grammarly, HTTPS Everywhere, MalwareBytes Browser Guard, Privacy Badger. Help will be greatly appreciated, thank you.

Here is the log:
