JS:Downloader-FVX[PUP] Virus - How do I get rid of it?

Also, now I uninstalled Chrome to try to reinstall it. I was using MS Edge to download a new Chrome file. Now the PUP virus has attached itself to the Edge browser.

Good Evening. AVG Support helped me with this problem last Friday, but it's back. It seems to be attached to Chrome. I've googled for answers but cannot find any. I did reset my Chrome browser back to default settings but the problem remains.

It pops up with almost every website I go to or email I click on. Mailchimp, Infusionsoft, etc. I tried to attached an image of the pop-up here but cannot.  Any thoughts on how I can get rid of this for good? Thank you. 

 
Thank you! I did what you suggested. It took a long time and found a lot of stuff to quarantine. I'm hopeful this is it. Thank you. :)

We're sorry to know that, Jan. In this regard, we'd suggest you to try running a boot time scan using AVG. To do so : Open AVG - Click on gear icon beside Scan computer - Click on Install below Boot time scan - Run on next reboot - Restart computer.
Before proceeding to run a boot time scan, ensure that you've set AVG to fix the unwanted applicatons automatically. To do so : Open AVG - Menu - Settings - Basic protection - Detections - Under 'What to do with', click on Potentially unwanted programs & choose Fix automatically.

Our pleasure, Jan. We appreciate your efforts. Thank you for updating the status. Have a great day!
