Como has an encrypted virus with some messages in it.
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.
An encrypted virus that contains the following text message:
I'm a non-destructive virus developed to study the worldwide diffusion rate. I was released in September 1990 by a software group resident near Como lake (north Italy). Don't worry about your data on disk. My activity is limited only to auto-transferring into other program files. Perhaps you've got many files infected. It's your task to find and delete them Best wishes
