Vista - Mum's computer got virus.

Not really a virus,its an "anti" virus named antivirus 2010,
Keep asking my mum to pay to clean the infection.
Ofcouse,we are not stupid..everyone know that this "anti" virus is a fake one and all they want is money..
I tried to use spydoctor,it cannot clean it..
i tried to use AVG,it cleaned it on the first day but then another day the antivirus thing pops up again..
If you delete it,it reinstall itself..
Most annoying thing is that,
After a certain time using her computer,the antivirus will pop up and say "your computer is infected with serious virus..blah blah blah...and it you have to turn your computer off to prevent the damage(something like dat..)"
And there is 2 option "Get Protection!"(paying money) "ok"
And u cannot move that window,cannot close it..so u have to click ok-.-...

Is there any thing that can clean these virus?
My mum is getting annoyed by it...
My mum is not a safely computer user...
Her laptop also got the msn virus,which auto sends message to other and give them a link which contain virus...
Can anybody help with that too?Thanks.

Im sorry for annoying you,but my mum's computer is chinese,and so the programme itself installed it as chinese aswell...but its not the type we usally see...and it seems like...there is some error displaying the word..its not understandable,i tried to reinstall..i choose english but thats only for the installing process...
Can you perhaps show me some picture so i know which is "quick scan"?Thanks!

Update it first.



Don't just run a Quick Scan, Run a Full Scan.

it can be anything but from your information the infection might be come from spyware or malware just make use your anti virus and do scan daily and uninstall any software or application you no longer need and try system restore if you want but restore it before any change you did to the computer or take XTREME action like reinstalling your computer can be the last thing you have to do
