/noopera

Spybot - Search & Destroy

Command Line Edition (Immunizer)

The parameter /noopera tells the command line edition immunizer to not apply any actions to Opera profiles. To only exclude parts, you may use /nooperacookies for no cookies, /nooperadomains for domains, and /nooperaplugins for plugins.

For proper Opera 9.5 support, at least version 1.6 is needed.
