I have had a false positive though I am not too sure with Pand Av online scan where it said there was a file called pinstall.dll in my windows directory but no matter what I did I just could not find it at all. I am not sure it if is a false positive or not actually. every search I did in google acknowledged that if there is a file with that name it would be in the Windows folder but there was nothing there and so I had to chalk it up to false postiveness.
