7656i1C83C77D701DAF82  I just finished running Secunia's OSI program and found out I need to upgrade my copy of Adobe Reader to version 9.3.4.  When I saved the upgrade file, Norton Insight alerted me that the file's Reputation Level  is unproven.  How can I make sure the file is safe to install or should I wait a few days for Insight to update?
