You will find instructions for the removal of Win 7 Total Security ( it has many names ).
You will be prompted to download both rkill
and Malwarebytes Antimalware
. Both of these can be downloaded on another computer and copied to a flash drive. Take the flash drive to your infected computer and run them both.
Malwarebytes will ask to update after installation. As you cannot access the updates, please just go forward with scanning your computer and post the logs from both.
