This is a family of seven simple viruses. Most of them are only able to infect very short programs (shorter than the virus), but longer files will simply be overwritten.
Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.
More information on scanning and removal options available in your F-Secure product can be found in the Help Center.
