Based on the settings of your F-Secure security product, it will either automatically delete, quarantine or rename the detected program or file, or ask you for a desired action.
If ransomware uses encryption to take files or an entire system hostage, the encryption may be sufficient to make it very difficult to decrypt the files without the necessary decryption key.
In such circumstances, the recommended course of action is to report the crime to the relevant authorities and restore the affected data from a backup.
Security programs will sometimes unintentionally identify a clean program or file as malicious if its code or behavior is similar to a known harmful program or file. This is known as a False Positive. In most cases, a False Positive is fixed in a subsequent database release.
Usually, updating your F-Secure security product to use the latest database is enough to resolve the issue. You can check by first updating your F-Secure security product to use the latest detection database updates, then rescanning the file.
After checking, if you still believe the file is incorrectly detected, you can submit a sample of it to F-Secure Labs for re-analysis.
NOTE If the file was moved to quarantine, you will need to first collect the file from quarantine before you can submit it.
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.

Users may encounter Cerber ransomware in a number of ways:
Cerber ransomware will often use social engineering. This usually involves making the file, spam email or fake website look legitimate or desirable enough to lure the user into voluntarily running the file.
Once launched, the ransomware will silently encrypt files on a computer, essentially 'scrambling' the contents of the file so that the user can't access it normally without a decryption key that can correctly 'unscramble' it. This type of ransomware is known as crypto-ransomware.
Depending on the type of ransomware involved, the user may be able to take further actions. In most cases however, the encryption used to hold the content or computer hostage is extremely difficult to break, making recovery impossible unless a) a clean, recent backup is available, or b) the decryption key is obtained.
In such circumstances, the recommended course of action is to report the crime to the relevant authorities and restore the affected data from a backup. Precautionary measures should also be taken to protect your content and machine from being vulnerable to ransomware in the future. For more information, see:
