Okay, so when i downloaded the RAT, the person disabled my "Administrator Permissions" I'm not really sure how, but i have it enabled now though.
He also kept opening up CMD and folders, so i kept pressing Alt + F4 so he could do anything,i believe he tried deleting ESET, thank god you can't delete it so easily, after that i restarted my computer, and it had an update, I'm not sure if the update was caused by the RAT or just a legit update. (it was a pretty small update)
