As of yesterday, i seem to have caught a malware/adware on my firefox browser, it is the bing toolbar, very annoying , slows down my browsers and keeps poping up adds and additional pages, i came here to ask how to remove this annoying rubbish.
I have tried the standard methods which usually worked uptill now like : Search for the add-on in firefox, didn't FIND a bing toolbar, then i went to the control panel searching for any bing program, nothing there, i have also installed Malwarebytes Anti-malware to remove malware, after a scan it found some 170 threats, so i quarantined and restarted my pc, thinking it's all fixed, to my unpleasant surprise, when i reopened firefox i find that annoying as HELL ad in the top right corner of my broweser constantly prompting to open. I inspected the element and got this url : 'http://d2rqxm8q23j7p8.cloudfront.net/scripts/pagepeel-i/peel-ad.svg'
I need help to FIND this malware/adware and remove it, i know it is a bing type ad, and i changed my setting to show hidden files and folders but i cannot find it all the same.
Please help me get rid of this trash, i don't want to be forced to switch to chrome

Thank you.
