Manual removal:
To remove an entry from the IE context menu, run regedit and navigate to
this key:
[HKEY_CURRENT_USER\Software\Microsoft\ Internet Explorer\ MenuExt]
Your entry will be a subkey of that key. Select the MenuExt key and export
it (just to be safe) Then select the unwanted subkey and delete it.

You should also suspect the presence of other unwanted files or programs and
run (at least) these two programs:
Ad-aware from

Spybot from
http://security.kolla.de/
Both should be updated before use.
