Removal

Automatic action

Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.

More scanning & removal options

More information on the 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.

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 Alarm or False Positive (FP).

For example, 'tmp.edb' and other '.edb' files stored at the location 'C:\WINDOWS\SoftwareDistribution\DataStore\Logs\' may be unintentionally detected as malicious by various security programs.

Checking for a fix

In most cases, a False Positive is fixed in a subsequent database release; updating your F-Secure security product to use the latest database is enough to resolve the issue. If you suspect a detected file may be a False Positive, you can check by first updating your F-Secure security product to use the latest detection database updates, then rescanning the suspect file.

Send a sample to F-Secure Labs

After checking, if you believe the file or program is still incorrectly detected, you can submit a sample of it to F-Secure Labs for analysis and correction:
