Certificate Access is denied - Need help!

[Adam Young]

Hi all,

I've just installed Unity 5.4.0b24 but can't even open it due to Certificate access.
This is the exact error message I get :

"Copying C:/Program
Files/Unity/Editor/Data/Resources/DefaultCACerts.pem to
C:/Users/Adam/AppData/Roaming/Unity/Certificates/CACerts.pem:
Access is denied."
Could my Patriot blast SSD have issues?

I've had similar Certificate errors in the past (Graphics drivers struggle to update aswell).

HP Elitebook 8570w / i7 / Quadro 2000M / Win 10 / 16Gb RAM / 500Gb SSD (Recent upgrade, problems started after)
Comodo Firewall (Could there be an issue here? )
Panda antivirus

Thanks for any helpful input!

UPDATE : Been fiddling about.. Tried opening my credential manager.
Got this error..
"Credential Manager Error
You do not have permission to save files to this location. Select a different location.

Error code: 0x80070005
Error Message: Access is denied"

Performing a MS safety scan now for malware.. Any ideas people?
