Making Email Safer and More Efficient The Spirus service by Assure Data removes 98% of the spam before it reaches your desk. A current list of those outlets who email spam commercially or who have been duped into spamming is maintained. Any mail from these locations is blocked and removed before it reaches your desk. The user can add or delete locations from this list. You do not have to spend time and effort cleaning up your email box once, twice, or multiple times per day! In addition, any known viruses (based on five different virus company definitions) carried by the email are removed before you receive that email. It is a safer and more efficient way to email.
