Windows 7 Serious Problems.

[tamsynxx]

I'm trying to fix my mum's laptop. It's a HP ProBook S-Series (I know I told her it wasn't a good idea!).
Anyway, I'm thinking that she hasn't activated the windows 7 or has got a mega virus.
She gets an error in the bottom right hand corner saying the windows isn't genuine. The laptop will not let us do anything in the way of system restore, downloading or opening programs, windows update, HP support assistant or anything like that. We are faced with errors about environmental variable locations each time we try to do anything.

It won't even let me do the Microsoft Diagnostics and shows this error:
C:\Users\mumsname\appdata\local\microsoft\windows\temporary internet files\ content.IE5\S7687CZ2\MGADiag.exe
The system could not find the environment option that was entered

Can anyone give any advice or possible solutions? It seems like there is so much going on here. Please bear in mind that for some reason the computer has absolutely no administrative rights at all even though the user I am on is displaying that it is the adminstrator.

Have wasted nearly 8 solid hours on this today and get truly annoyed with it (to not use foul language).
Please please help? I'm ready to throw the damn thing out the front door.

Just for grins to knock out the possibility of a virus try this:

Do a full scan of your system using: Microsoft Security Essentials - Free Antivirus for Windows

Afterwards: Malwarebytes : Free anti-malware download

If nothing pops up for both of those,

And then also please post back results.
