When an infected program is run, an 'European Cracking Crew' -logo screen will sometimes be displayed. The screen is made of graphical characters and includes the following texts:
This program is cracked by Notice this: TS ain't smart at all. Distribution since 11-06-1987 (or 06-11-1987) Press any key
There are several variants of this virus, and the message varies depending on the variant.
Note that this virus has nothing to do with the "Join The Crew" hoax message.
Depending on the settings of your F-Secure security product, it will either automatically delete, quarantine or rename the suspect file, or ask you for a desired action.
More information on the scanning and removal options available in your F-Secure product can be found in the Help Center.
