Spy Sweeper Conflict w/ XP Pro Design

I installed SS as an Admin User. I would like to use SS for real-time protection as I surf the web from my Limited User acct.

Webroot on-line help states:"you must have Admin Privileges for the acct that you use to log onto yr computer. If you do not have Admin Priv you will not be able to start SS."

Is there a way to activate SS from the Limited User accts?? Or:
1. millions of SS buyers are surfing as Admin Users (crazy)
2. people are buying SS just for on-demand scanning (expensive)

I appreciate any help solving my Limited User issue.
