Virus/Malware

[Little Butch]

I'm not an idiot, nor am I a computer whizzkid. So I'm after a bit of help...
My girlfriend's just bought her Laptop over and it seems o be infected with sh*tloads of 'stuff'!
I downloaded Malwarebytes and ran that which flagged up over 1300 'things' which I quarantined. AVG 2013 was already on the laptop which just popped up itself saying there's a couple of trojans which I removed as well.

Yet I'm still getting loads of popups on chrome. How do I solve this?
One popped up just now saying I need to update windows drivers....


Thanks.

Just run malware bytes in safe mode this time. Picked up a couple more things! I'll run it again in safemode just to be sure.
Still bringing some popups up. What's combo fix?
