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