(Apologies if the formatting is problematic, my first post).

1. Stop the service:

    sc stop VisualDiscovery

2. Open up your favourite process manager and remove any superfish processes (containing the word superrfish).

3. Perform the uninstall via Add/Remove Programs (under superfish)

4. Confirm %ProgramFiles%/Lenovo/VisualDiscovery is deleted.

5. Open System32 and confirm there are no files beginning with VisualDiscovery

6. Open AppData and confirm that no files start with VisualDiscovery

7. Remove certificates (Firefox and Global).

8. Remove from Registry: HKLM\SOFTWARE\Wow6432Node\VisualDiscovery.

After that, VisualDiscovery should be fully removed.
