Was this a virus?

Hey guys!

So tonight I ran into a fun situation... I went to install Warframe off of Steam. However, when the game was installed, it said it needed admin to allow firewall access. Usually a UAC window would come up and I could allow this. However, nothing came up. I think tried to augment my UAC settings, but found I had ZERO control over any of those settings. I was unable to change my Admin password, I was unable to change account type, unable to add a new account. 

I ended up doing a Windows 'Refresh' with the install disc, now everything is back up and running.

Was this just me being derp or was there some foul play at work? Any thoughts?

Windows 7?

No, Windows 8. 

I think you need to lay off the scottish goat porn.
