This is a large Polish virus. It infects files in the same way as Vacsina - COM files are infected normally, but EXE files are converted to files with COM structure, by adding a small, 139 byte loader program to them.
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.
