Let's start with which McAfee product are you using? The latest version of the consumer product lets you whitelist files, so you can tell "McAfee" to ignore the detection.
Anti-Spyware/Malware & Hijacker Tools may be able to assist you in resolving your issue. May I first suggest you to try running McAfee Stinger.......then try GetSusp also included within......then run the free version of Malwarebytes
Should these sucessfuly clean up the trojan you could refer to What To Do When McAfee Detects Software As An Infection - How to Submit To McAfee Labs & Appeal
