A legitimate file was inadvertently detected as 'infected', 'malicious' or 'suspicious' (also known as a False Positive or a False Alarm).
If you are certain that the file detected is a legitimate application file, you may choose to exclude it from scanning.
You may also send a sample of the suspect file to F-Secure Labs for further analysis via our Sample Analysis System (SAS), specifying that you are submitting a false positive. Any additional information such as the origin of the file, scanning report file, and false positive detection name will help to resolve the issue more quickly.
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.
