AVAST v/s antimalwarebytes

Hello,
I try to kill “PUP.OPTIONAL” with the soft called “antimalwarebytes” It is not easy.
My question is "How do you explain that AVAST does not show those malwaere ?

Best regards

sorry but i dont see my previous post 8

A “PUP” is not a virus or malware. It is a potentially unwanted program/item.

Malwarebytes reports it but at present fails to remove it correctly.

You can read about PupOptional here >> http://www.fixyourbrowser.com/removal-instructions/pup-optional-outbrowse-remove/

Thanks for a very good information that I’ve not found by myself

avast PUP scan is default off in all scan exept boot scan…

when you scanned / detected with Malwarebytes, was it marked for removal ? …did you click the remove selected button after scan ?

if you need help removing it, follow instructions and attach logs http://forum.avast.com/index.php?topic=53253.0

And can be turned on as shown in the attached screen shot
