FriendGreeting is an e-card service that behaves similar to an email worm once installed, although it could also be seen as a PUP. Upon execution of the installer, the user will be asked to approve the associated certificate and accept the EULA. The EULA contains a clause that permits access to Outlook's notebook, which somewhat permits the subsequent worm-like spreading routine. An email will be sent to all email addresses that can be retrieved from Outlok, with the following message. The program will also add the following registry key: “PMedia”=”C:Program FilesCommon FilesMediawinsrvc.exe”
