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.
Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.
