Unable to remove Adware.Yontoo, usual fixes not working


Recommended Posts

Hi all,

 

Recently I started seeing Malwarebytes alerts me every day on some addware, and after qurantine/removal it keeps coming back.  I did some searching and found this:

Several times making sure to follow directions (i.e. make sure Chrome is closed during scan etc), rebooting but its still there.  Then I got AdwCleaner which claimed to fix it but Malwarebytes still finds it.  Also tried Avast, which doesnt find anything.  Attaching FRST.txt as directed.

 

HALP!

Hi,

Thanks for posting in the Malware Removal for Windows Help forum. Being infected is not fun and can be very frustrating to resolve, but don't worry because we have a team of experts here help you!!

Note: Please be patient. When the site is busy it can take up to 48 hours before a malware removal helper can assist you. If no one has replied to your new topic after 48 hours please contact an Administrator to let them know.

First, if you haven't done so, please run a Threat Scan with the latest version of Malwarebytes. This may resolve your malware infection issue without the need for additional support. Click "Reveal Hidden Contents" below for details:

  4. Click Start Scan
     

Next, if you're still experiencing issues after running Malwarebytes, then technical logs will be required to assist you. Click "Reveal Hidden Contents" below and follow the instructions to run the Farbar Recovery Scan Tool:

Don't use any temporary file cleaners unless requested - this can cause data loss and make a recovery difficult.

Please download the Farbar Recovery Scan Tool here and save it to your desktop. Note: You need to run the version compatible with your system. You can check here if you're not sure if your computer is 32-bit or 64-bit

  1. Double-click to run it. When the tool opens click Yes to the disclaimer.
  2. Press the Scan button.

  3. It will make a log (FRST.txt) in the same directory the tool is run. Please attach or copy and paste it to your reply.
  4. The first time the tool is run, it also makes another log (Addition.txt). If you've run it before it may not and you may need to select it manually.
     

Finally, attach the Malwarebytes Threat Scan, FRST.txt and Additional.txt logs to your reply. Before submitting your reply, be sure to enable "Notify me of replies" like so:   notify me.jpeg

Make sure you execute all the items including  9 to 11.
Close your Chrome browser.
Do NOT enable sync yet, as you need to perform another scan with Malwarebytes first in order to fix Chrome.
Perform a new scan with Malwarebytes and let it delete what it has found.
Reboot in case it asks to reboot.
===

If that fails look at the secont post.
Foollow the instructions.

Let me know how it goes.

Yes, i have done all of this, many times.  Both steps  - it's still not working.  I appreciate the help but I just want to make it clear that I have already tried these things with no luck at all.

 

Also I would like to point out that after this step:

  1. Perform a new scan with Malwarebytes and let it delete what it has found.
  2. Reboot in case it asks to reboot.

Verify after a next scan the detection doesn't occur anymore. If results come back clean, you can enable Google Sync again.

That last entry is not really complete is it  - it says "if" the results come back clean but nothing at all about what to do if it does not come back clean.  Which is the state I am in right now.

Even before starting Chrome again (the program is not running and still has sync disabled)  it finds the adware again.  I can Quarantine, Delete then Scan and they will come right back.  All without ever touching Chrome, which has had all of the steps in that artice complete and never started between scans.

Here is what the (almost comical) sequence looks like:

 

1 - follow the steps in the article to the latter

2 - Reboot

3 - Scan, find adware, quarantine and delete. Reboot

4 - Scan, find adware, quarantine and delete. Reboot

5. Scan, find adware, quarantine and delete. Reboot

6 ->> Infinity (I am guessing, I gave up after 5 tries)

Is it possible this instance needs attention outside of Chrome?
