Please click on (download) and run Rkill from the following link which will terminate known bad processes and reverse a lot of harmful/unusual settings changes: http://www.bleepingcomputer.com/download/anti-virus/rkill You will want to click on the link that says “iExplore.exe Download Link” and select Open or Run. Once you start running it, it should take less than 1-2 minutes to run.
Then, please go to this page: http://ow.ly/6fNiP (Type exactly as it appears if you cannot click it) and download Malwarebytes for free. Simply click on Download file under the download link and forum link. Download, save, and run (install) it. You do not have to pay for the program at any time. It may prompt you for a trial; click “Decline”. Malwarebytes will then download updates, and then run the Quick Scan (Perform quick scan > Scan) and "Remove Selected" if it finds any items.
Let me know how it goes; thank you.
