This virus is not particularly interesting, despite the size. The reason it is so large is simply because it is written in some high-level language, possibly Pascal, which makes analysis a very time-consuming task.
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.
