is this:

Show Hidden Devices under Hardware Device Manager in your Windows Control Panel.
Look for "TDSSserv.sys". If found, right-click it then select disable. Do not select uninstall but choose to "disable"
Reboot the pc.
Scan the system using up-to-date antivirus or anti-malware.

If the problem continues, I suggest to send your log in Malware Removal forum over Malwarebytes Forum.
