It's the strangest thing I have ever seen... Windows 8.1 x64... Any Norton installer I access with this machine is lacking the digital signature. The checksum matches what it should be. I put the installer on a flash drive and plugged into a Windows 7 machine it is fine. Plugged into the Windows 8.1 machine it is missing. It also refuses to run. I have tried this with an older installer I had already on the drive, same results. Every other file I have on the drive that is signed works ok. Scans with KIS and MBAM do not find anything. Has anyone else seen this before? ---Nevermind, it's working now for whatever reason. This can be locked or deleted as far as I am concerned. --I take it back, still doing it. Very strange.
