Issue with MG windows XP Cleaning procedure..

Hi,
I was performing the Windows XP Cleaning Procedure (post http://forums.majorgeeks.com/showthread.php?t=139313)
But It failed on running the combofix software;due to AVG 8.0 could not be stopped and combofix requires to do so.
I reboot and tried to unistall the software:
when trying to uninstall AVG I get the following message,

Local machine: installation failed
Installation:
Error: Action failed for registry key HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows: creating registry key....
Error 0x80070005

The original problem was that windows is slow when booting up (about 6 minutes) this problem began about 1 month ago, I have uninstalled itunes because it loads up a lot of memory but it hasn't improved a bit since uninstall. So I was going for the general performance maintenance but it get stuck there, the previous software checked have not found anything except Malaware found 9 registry Keys Infected; 1 Registry Value Infected; and one file infected (all related to popcaploader.dll ); that were fixed with the same software.

I have a sony vaio VGN FS742/ w
Windows XP
1.73 GHz
1.99 Ram
Im using about 48% of space of my HD.

 

Please help, if you could provide any help it would be great, now the computer is even slower then it was before.

thanks

How about using Revo to uninstall AVG

Then run Ccleaner to make sure it's gone
Reboot now try combo fix

 

Hi,
Thanks for your answer.

I tried Revo but when trying to uninstall the application I got the same error message, I'm not sure I should go on with the following Revo uninstall following steps since I have got the installation failed message in the previous steps.
