Sophos keeps showing "Sophos Protection Disabled"

Hi, im new here so any help greatly appreciated.  Following having a fake AV virus (Internet Protection Virus), i think i have finally cleared most of it off, i now have two isuses.

Sophos keeps showing "Sophos Protection Disabled" - i have read the various threads and the programme shows it turned on when i open it, i have re fun the almon.exe but after a few seconds its back to disabled.

the second issue is that the scanner will not allow me to do a rootkit scan, it hangs on 2% and goes no further.

I have run a normal scan excluding the root kit and there are no viruses detected but it says that it cant access the c:\users ntuser.log1 file or ntuser.log2 file.

Any ideas would be appreciated. Mat
