Summary

Removal
Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.
A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:
Check for the latest database updates
First, check if your F-Secure security program is using the latest updates, then try scanning the file again.
Submit a sample
After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.
Note: If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.
Exclude a file from further scanning
If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.
Note: You need administrative rights to change the settings.
Technical Details
When an infected document is opened the virus infectes the global template and modifies the current user settings as follows: User name is changed to "OPEY A.", address is changed to "CNNHS B'92 PHILIPPINES (CNSC)" and initials are changed to "LOVE". It also removes the "Tools/Macros" and "Tools/Customize..." menu selections, "ALT-F8" and "ALT-F11" keyboard shortcuts, and disable the "Visual Basic" toolbar.
After the global template has been infected, the virus will infect every document that is opened, closed or saved thereafter.
The virus activates its payload at the holidays mentioned below. It then adds a message to the end of "C:\AUTOEXEC.BAT" file, so the message will appear when the system is restarted.
At December 25th and January 1st the message is:
MERRY CHRISTMASS AND A HAPPY NEW YEAR !!! from: OPEY A.
November 1st the message is:
HAPPY HALLOWEEN !!! from: OPEY A.
and February 14th it will be:
HAPPY VALENTINES DAY !!! from: OPEY A.
Then the execution of "AUTOEXEC.BAT" will stop until a key is pressed.
