Spybot error message in Windows 7

[Issy Rule]

I have the Google redirect virus - Spybot is the only one to actually detect these but when I run it as administrator and then try to remove the viruses I get the error message: c://windows/system 32/drivers/etc/hosts access is denied.
Any help would be appreciated.

Hello,

Please delete your old host file.
It should be stored here:
Windows 2000/XP/NT: C:\windows\system32\drivers\etc

Then download a new host file from this site.

This is how to do it:
Create a new txt file with notepad on your desktop.
Therefore right click your desktop, choose "New", then choose "Text Document".
Name it hosts. Then right click and choose rename.
Now remove the .txt so that you have a file without any extensions, just named hosts.
Then go to this site.
Mark the whole text. Then copy the whole text.
Open your new hosts file and insert the copied text here.
Save the file.
Now move the file by copy and paste to:
C:\windows\system32\drivers\etc
