This virus appears to have been written by a technically proficient, but sloppy author, as there are several mistakes in the code, including one which prevents it from working under any version of DOS other than 3.3.
LoveChild only infects COM files, overwriting the first 4 bytes and adding 488 bytes to the end. When the virus is active, it may delete files being executed. It may also overwrite the beginning of EXE files with a Trojan which will format the hard disk if it is executed.
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.
