Brit Method Virus

I have been infected with this annoying virus.
Is there any way to remove it for unfortunately AVG Free does not see it and reports that my machine is clean.

Hello Jon,

We are sorry for the inconvenience caused.
May I know how did you confirm that your PC is infected with "Brit Method Virus" ?

Every time I open Google, it is the first page that opens.
From all my research it is a virus. There are several methods of removing it but I would have hoped that AVG should find and protect me.


Yours sincerely,

Jon Leigh
