No Manusia123,
I do not think there is anything wroing with that file, just the protection packer generically flagged by an av solution. Probably a false positive, flagged as a virus but a false find so to say. I agree with you that Quicktime had a lot of security issues in the past and you are better of with an alternative. So the uninstall is your decision and not a bad one, then you have no further use of DeleteMe1.exe also and can safely delete it,
