AdwCleaner does not remove PUP.Optional.Legacy

Recommended Posts

Hi , while running AdwCleaner it detected a PUP.Optional.Legacy registry value that seems related to Internet Explorer toolbar. [HKLM\Software\Microsoft\Internet Explorer\Toolbar|{32099AAC-C132-4136-9E9A-4E364A424E17}]Upon quarantine and restart of computer, AdwCleaner shows that the item is still not fixed.

I've tried disabling extensions on IE and running scan again but the PUP remains unfixed. When I reset IE settings and re-scan, a new PUP.Optional.Legacy registry key shows up additionally but I am able to quarantine it successfully leaving behind the PUP.Optional.Legacy registry value that I can't seem to fix. I've tried running scans using Malwarebytes, HitmanPro, Sophos Virus Removal Tool and ESET but this PUP does not show up on any of them.

My default browser was Chrome. I've reset settings and sync data but the PUP is still there and can't be fixed. My computer is an old computer that I've recently started using, I have Internet Explorer 9 which doesn't have sync if I am not mistaken. Should I proceed with Farbar?

Hi, I'm not sure how or where to select the 32 bit version, when I click on download I seem to automatically get the 64 bit version. 

I did not see any popups or push notifications as I have not actively been using Internet Explorer. The PUP showed up in a scan and I was worried it would be harmful as it could not be removed.

Please download the attached Fixlist.txt file to  the same folder where the Farbar tool is running from.
The location is listed in the 3rd line of the FRST.txt log you have submitted.

Run FRST and click Fix only once and wait.

The Computer will restart when the fix is completed.

It will create a log (Fixlog.txt) please post it to your reply.

Please post the Fixlog.txt.

If the problem persists and Chrome is Synced with other Devices reset it.


Execute the suggested fix.

Restart the computer normally.

Is the problem solved?
