Problem Solved
The problem was down to the Host file, once i had removed all reference to comodo in the host file i was able to activate Antispam, Backup and i-Vault.
This was with Firefox as the default browser?
The host file can be located at:
Windows XP
C:\Windows\System32\Drivers\Etc
Windows NT/2000
C:\Winnt\System32\Drivers\Etc
Windows 95/98/Me
C:\Windows
Right Click on the Host file and select EDIT.
To comment out an entry in a hosts file, simply add a # before the entry.
For example, if the hosts file had:
195.62.24.1 secure.comodo.net
You can add the # so that it looks like this:
#195.62.24.1 secure.comodo.net
Or you can delete those entrys, then save the Host file.
Thanks to Little Mac for the answer.
