Gpcode.AK is "ransom-ware" that intends to extort money from the victim by encrypting data files. It requires the victim to order the malware author's custom tool to restore the encrypted data.
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.
Gpcode.AK searches drives C to Z for the following file types on the system:
It then encrypts the discovered files using an RSA algorithm and renames them with a ._CRYPT extention and deletes the original files. As a ransom note, it drops the file !_READ_ME_!.txt to the directory that requires the victim to buy a custom decrypting tool from the malware author.
