Dregol and coupons pop-ups

Hi Peter. I apologize for the inconvenience caused to you. The unwanted toolbars and search engines in your web browser will get installed without your knowledge when you install a third party application or click inadvertently on a download link. Since the installation of the application will be after your approval, the AVG Internet Security will not be able to block the program. However, if the program tends to be malicious, the AVG Internet Security will quarantine it and let you know. In most cases, such addons and toolbars are not dangerous but definitely annoying. To prevent this from happening again, you can install new applications using ‘Custom installation’ rather than ‘Standard’ or ‘Express Installation’. In this way, you will be able to know if any unwanted applications are being installed in addition to the program you want.

Despite AVG scan finding no malware any browser (explorer and firefox) a dregol search tab appears as do coupons.
Can you help!
