Automatic action

Once detected, the F-Secure security product will block the suspect file until further user confirmation is received.


If you are aware of and accept the potential risks, you may choose to exclude this program from future scans by the F-Secure security product.

If you suspect a file has been incorrectly identified as malicious, (that is, it is a False Alarm or False Positive), please first ensure your F-Secure security product is up-to-date with the latest detection database updates, then rescan the suspect file.

If you continue to suspect a False Alarm, you may submit a sample of the suspect file to our Security Labs for further analysis via the Submit A Sample (SAS).
