This virus infects programs by overwriting them, but unlike most overwriting viruses it will generally not destroy the host program. This is because it will only overwrite unused areas within the program. The virus searches for a block of at least 416 zero bytes, and places itself there. As such programs are rare, this reduces the chances of the virus spreading.
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.
