Here are the next 2 steps, more steps will be needed, after I see the results of these logs.
Run them in this order.
Step 1: Run AdwCleaner
Close all open programs and internet browsers.
Double click on AdwCleaner.exe to run the tool.
In the results tabs, uncheck anything you don't want to remove.
Click on Cleaning.
Confirm each time with Ok.
Your computer will be rebooted automatically. A text file will open after the restart.
Please Copy & Paste the contents of that logfile with your next answer.
You can find the logfile at C:\AdwCleaner[C1 or later].txt as well.
Step 2: Run Malwarebytes Junkware Removal Tool
Download Malwarebytes Junkware Removal Tool onto your Desktop. If your default download location is not the Desktop, drag it out of it's location onto the Desktop.
Warning! Once the scan is complete JRT will shut down your browser with NO warning.
Shut down your protection software now to avoid potential conflicts.
Temporarily disable your antivirus and any antispyware real time protection before performing a scan.

Run the tool by double-clicking it. If you are using Windows Vista or Windows 7/8, right-click JRT and select Run as Administrator.
The tool will open and start scanning your system.
Please be patient as this can take a while to complete depending on your system's specifications.
On completion, a log (JRT.txt) is saved onto your Desktop and will automatically open.
