What to do

Try the following, in order:

• Reboot the computer.

If rebooting does not work,

• Check for the presence of the file: %windir%\temp\SophosRebootTest.txt
• If you find it, delete it.
• Install Sophos Anti-Virus.

If problems persist, check the following registry entry:

Please read the Warning about editing the Windows registry before making any changes to the registry. Only edit the registry if you are confident that you can do so safely.

• Check the registry entry HKLM/Software/Sophos.
• If it incorrectly reports that an old version of Sophos Anti-Virus is present, delete the entry.
  1. If you are unable to delete this entry, give everyone full control over the entry, then propagate that change to all child objects.
  2. Delete the registry entry.
  3. Remove the following registry keys:
     HKLM\Software\Sophos
HKCU\Software\Sophos
HKLM\System\CurrentControlSet\Services\InterCheck* (remove all entries that begin with InterCheck)
HKLM\System\CurrentControlSet\Services\SWEEP* (remove all entries that begin with SWEEP)
HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall\Sophos-SweepNT
  4. Under HKLM\System check all 'ControlSetXXX' entries (for example ControlSet002\Services). If you find an entry that contains 'InterCheck' or 'SWEEP' delete that entry.
  5. Reboot the computer.
• Install Sophos Anti-Virus.
