A legitimate file was inadvertently detected as 'infected', 'malicious' or 'suspicious' (also known as a False Positive or a False Alarm). Details of the database updates that contain fixes for the latest known False Positives are listed below.
False Positive Fix
In most cases, a False Positive issue is fixed in a subsequent database update; updating your F-Secure security program to use the latest database is enough to resolve the issue. Details of the update containing fixes for the latest known False Positives are listed below.
Instructions on how to check if your F-Secure security program is using the latest database update are available in Community: How do I know that I have the latest updates?
If you are certain that the file detected is a legitimate application file, you may alternatively choose to exclude it from future scans by the F-Secure security product.
More scanning & removal options
More information on scanning and removal options available in your F-Secure product can be found in the Help Center.
You may also refer to the Knowledge Base on the F-Secure Community site for further assistance.
False Positives sometimes occur if a program contains code or behavioral routines sufficiently similar to known malware to be deemed a security risk, particularly if the program uses file compression or protection utilities known to be associated with malware, or is spread through a site or distribution mechanism known to be associated with malware.
