Think I have a RAT

So I recently received a very suspicious file from someone via AIM, I made sure not to run it but neglected to delete it before other people got their hands on the computer so it may have been run. After examining the file in HxD I saw a bit about the window style being transparent, it also came up as infected in both McAfee and MalwareBytes. Although I currently have no symptoms I need to make sure I have privacy and security. If needed I can provide a copy of the file as well.
