This virus is not to be confused with the "Warrior" virus, which is unrelated. Brainy (or Warrier) is unusual in one respect - it is one of the few viruses that don't change the beginning of the programs they infect.
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.
