I have just downloaded the latest Win 10 64bit driver for my ASUS DX card. When I boot my PC now it stalls the boot because of a message that pops up about C:\Windows\SysWOW64\HsMgr.exe and then another for HsMgr64.exe. I'm guessing this file is safe (downloaded twice) and the reason the message is coming up is because of something to do with digital signatures. How do I stop the message coming up and stalling my boot (other things like Steam boot after this message has been clicked)? I could follow this but I'm unsure if it's the right way to go: http://www.door2windows.com/disable-open-file-security-warning-message/ Any ideas chaps? Thanks in advance.
