Virus 'Global Patrol' removal

Hi
My computer is infected with 'Global Patrol'. It is only picked up with a
spybot search each time I start the computer and removed. It is located in
the computers xp VOLUME INFORMATION FILE, from where NOTHING can remove it
(so Far!) and launches into HKEY_LOCAL_MACHINE\Software\GlobalPartol. From
this location it is removed by Spybot but never from its generation point. I
have tried about 10 removal programs without success. If I forget to remove
it each time it tries uploads other viruses etc which get blocked by
PC-cillan.

What do I do other than reformat and reload? - With massive loss of data!
(As I cannnot burn to disc)
Please note I can only download 200MB/month!!! Which is gone in a few days -
Then on VERY slow - small pages only can be opened! Eventually!
