Run the trainer in administrator mode even though you might be logged on as admin. If you feel uncomfortable and not do not trust any of the above provided info, then please avoid using my trainers because i cannot help you then. My files are completely clean from any type of viruses or mallware and the like, they have not even been near to such and will not harm your system in anyway. If you are unaware of whats called 'False Positive' files then you may not be aware that these types of files are completely harmless and is infact just seen as such but are not.
My trainer may sometimes alert such applications as antivirus programs and malware programs, this is due to the protection used on most of my trainers.
