|I recommend Malwarebytes as a double check scan when you are not sure your antivirus program cleaned out everything. And I recommend Process Explorer from Microsoft to be able to see more information about processes that are running, and decide what to stop. It is best to scan when these suspected processes are not running, or in safe mode (where they shouldn't be able to start).|
You have to be a little bit crazy to keep you from going insane.
If all else fails, read instructions.
