Chrome PUP still active - TarkusZ


Recommended Posts

This just started on my MB3 upgrade also. This file is a SQLite database that contains user specific items and can be moved to other installations to preserve search preferences, plugins, etc.. More specific information on why this is now flagged would be appreciated. It was flagged 5 times for both users on this installation. I am guessing it had to do with a plugin/extension. For now I have not quarantined any of the items. I am setup to approved and actions found during a scan so I don't have Replaced (series of numbers) in my message. My guess is those are pointers to specific items in the file.

Hi,

First of all, for more explanation about why this issue is occurring, read Fatdcuk's post below.

Now, if you aren't running the latest version of Malwarebytes already (which is 3.3.1 at this time), please download and install the latest (in-place upgrade) from the website directly.

https://downloads.malwarebytes.com/file/mb3/

Alternatively, you can open Malwarebytes, go to the Settings tab, and under the Application tab, click on the Install Application Updates button. This way, Malwarebytes will look for a newer version of the program and if found, asks you if you want to install it (do so).

Once done, follow the instructions in the thread below and see if that solves your issue. Please note that, as stated in the thread below, these steps will most likely have to be executed on every single computer where you are logged in Google Chrome with your Google account, and where the sync feature is enabled.

If the guide above didn't help you, you can try to manually clean your Google Chrome settings, as to remove the threat Malwarebytes is detecting (the one(s) that keeps coming back). There are three main areas that you can clean: the New Tab page, the Search engine, and the On start-up (start page):

  • On the top-right corner of Google Chrome, click on the three little dots, and then click on Settings (or simply access chrome://settings from the navigation/URL bar)
  • Under Appearance and Show Home button, make sure that either New Tab page is selected, or that you know and trust the website in the second option (ex: google.com)

  • Under Search engine, make sure that the Search engine used in the address bar is set to Google or another trusted search engine (such as DuckDuckGo)

  • Click on the Manage search engines button, and under Default search engines, delete every other options (by clicking on the three little dots on the right, followed by Remove from list) other than Google

  • You are also free to remove the search engines under Other search engines if wanted
  • Once done, go back and under On start-up, make sure that the Open the New Tab page option is selected OR, if the Open a specific page or set of pages option is selected, make sure that only knowns and trusted websites are listed. Otherwise, delete them by clicking on the three little dots on the right and select Remove

Another possible solution at the moment, is to add the detected file(s) (either Web Cache, Secure Preferences or both) to Malwarebytes' scan exclusion list, so it won't get detected anymore. For more information on how to proceed, follow the instructions in the support article below.

https://forums.malwarebytes.com/topic/214438-chrome-web-data-pup-wont-go-away/

The two possible files to add are:

C:\Users\$YOUR_USERNAME\AppData\Local\Google\Chrome\User Data\Default\Secure Preferences
C:\Users\$YOUR_USERNAME\AppData\Local\Google\Chrome\User Data\Default\Web Cache


For instance, the full path for these two files on my system would be:

C:\Users\Aura\AppData\Local\Google\Chrome\User Data\Default\Secure Preferences
C:\Users\Aura\AppData\Local\Google\Chrome\User Data\Default\Web Cache

Let me know if any of that worked for you. If it did, let me know which solution worked. If you need assistance with the instructions above,
