Good Morning,

My apologies if these are duplicates.

DriverRestore | DriverWhiz (383media.com).  We caught this app sending user information (computer name, user name, user 
access level, etc) as part of the URI when communicating with the C2.  It's pretty aggressive adware, the type that 
finds problems that don't exist and expects payment to fix those non-existent problems.

[CS][May2016][PUP][CatA])"; flow:established,to_server; content:"User-Agent|3A 20|DriverRestore"; http_header; nocase;

These other two are user agents of aggressive adware as well.
