Greetings.
There are a few things I would like to address. None of them are malware related. Regarding CCleaner, there are errors present in the log files so I would like to remove the program.
The wrong drivers are installed for your NVIDIA graphics card. I suspect Windows Update automatically installed drivers but they are different than what the manufacturer calls for.
Please do these things. They are a bit more complex than normal so if you have any hesitations or questions please stop and let me know.
