Suspect a file is incorrectly detected (a False Positive)?

A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:

  • Check for the latest database updates

    First check if your F-Secure security program is using the latest detection database updates, then try scanning the file again.

  • Submit a sample

    After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.

    NOTE If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.

  • Exclude a file from further scanning

    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.

    Note You need administrative rights to change the settings.

Technical Details

The detection name Backdoor:W32/IRCBot is used to identify a member of a large group of programs that install a backdoor on an infected machine. The backdoor will then log onto Internet Relay Chat (IRC), the popular instant messaging (IM) system. It may then act as in IRCBot, a type of "bot" that an attacker can control from a modified IRC client.

IRCBots can be used for a variety of malicious actions, such as controlling backdoors or botnets. Backdoors allow a remote attacker to control an infected machine, while botnets can be used to harness a the collective resources of infected machines to perform more resource-intensive actions, such as sending out massive quantities of spam or launching major Denial of Service (DoS) attacks.
