Short Bio

PUP.Optional.FullTab is the detection for a few potentially unwanted Chrome extensions that are new tab hijackers. This means they control which site will open when the user opens a new browser tab on an affected system.

Common infection method

These extensions are promoted by adware and/or other potentially unwanted programs to trick the user into believing they are useful.


Malwarebytes can remove the files associated with these extensions, but the listing of the extensions has to be done manually in the settings menu of Chrome.
