welcome to the forum.

i suggest you try malwarebytes antimalware as a first step.

download install update and do a scan, don’t forget to remove what it finds. a system reboot might be needed.

second do a scan with OTL and post the result here

http://oldtimer.geekstogo.com/OTL.exe

Download OTL to your desktop.
Double click on the icon to run it. Make sure all other windows are closed to let it run uninterrupted.
When the window appears, underneath Output at the top change it to Minimal Output.
Under the Standard Registry box change it to All.
Check the boxes beside LOP Check and Purity Check.
Click the Run Scan button. Do not change any settings unless otherwise told to do so. The scan wont take long.
    When the scan completes, it will open two notepad windows. OTL.Txt and Extras.Txt. These are saved in the same location as OTL.
    Please copy (Edit->Select All, Edit->Copy) the contents of these files, one at a time, and post it with your next reply. 

good luck.
