Pop up malware

My Windows computer (Windows 10 Home) has malware that repeatedly pops up obviously false ads for McAfee, Windiws virus alerts, and more. They pop up in the lower right corner of my screen and stay on top of all windows. My browser is Firefox. Firefox extensions do not help ( WOT, Ghostery, AdblockerUltimate,, PopUp Blocker). I am also getting an "Ads by Google " banner across the bottom of the screen. All of the above, if closed, re-appear in a few minutes. Can anyone tell me how to get rid of this?

Thanks

Hi johnaubrey,
My name is Dennis and I will assist you with your computer problems.
Please read through these guidelines before we start.

• Back up any important data, as a precaution before starting this process.
• If you are unsure about anything then please ask. This makes the task much easier in the long run.
• Do not run any other tools or make changes to your system during the removal process.
• Please do not start a new topic and keep all replies in this thread.
• Follow the instructions in the sequence advised.
• Copy and paste the logs into the reply. I will advise if anything needs to be added as an attachment.
• Here at Bleeping Computer we are mostly volunteers, so please be patient with us. I’ll try to respond within 24 hours. You will be advised if it is expected to be longer than 48 hours.
• Please let me know if you are going to be delayed in responding. If you do not reply after 5 days, I’ll assume you do not want to continue and will close the topic.
• Sometimes things might seem to be resolved, but there may still need to be more checks necessary, so please wait until I give the all clear.

Firstly I'd like you to follow the steps outlined here: Preparation Guide
Section 6 covers how to download and run the Farbar Recovery Scan Tool (FRST).
Note: If you receive a warning about the download, it is a false positive and you can safely ignore it.
Please copy and paste both FRST logs into your reply. If you get an error message advising that the content is too long, you should post 2 separate replies.

Dennis

Dennis:

Thank you for our response. However, the problem has been solved in this way:

It's nothing to do with malware.

See:

Also:

Look at the above link and read instructions for Firefox. Instead of blanket blocking all notifications you could also use the "Remove all websites" button.

Your system will scan clean because there's nothing malicious to detect or remove. You've allowed notifications on some website and it's serving up those notifications.

Thanks again

I am pleased to hear that the issue is resolved now.

Thanks for letting me know.

I am closing this topic, as the problems appear to have been resolved.
