globalroot - IE7 virus

Hi there,

 

I have seen that there are some other people here with the same proble, - but I have somehow got a virus that displays a message each time I open IE, Firefox or Safari.  I'm sure that it goes alot deeper than this as well.  Is it safe to use the computer for banking/secure content etc? 

 

Could someone please help me remove this virus as I am not keen to re-format my PC?  Any help would be apreciated.

 

Cheers

Dan
