Hello,
It is understandable.
Often than not, most "educated" stuff gets flagged by your anti virus system.
In most cases, it is just a normal thing...
In the end though, however, it is a risk one must decide to take or not to when downloading "educated" stuff. Since you dont truly know where it comes from or whoever educated it. It is of course very easy to imbed something fishy in any indicator for that matter.
