The virus uses a complicated encryption method, which complicates detection somewhat.
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.
Variant:1226
An earlier variant of the Phoenix virus.
Variant:Proud
A 1302 byte earlier variant.
Variant:Evil
A 1701 byte variant.
So-called "M" and "D" forms of the variants have been reported, but this is actually a misunderstanding. The "D" form is just the decrypted virus and the "M" form is a sample file infected multiple times.
