    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.

Technical Details

Instant Messenger trojans are usually standalone programs that are sent by hackers to their potential victims in emails or instant messages. IM trojans are most frequently used to steal user's IM account information. When such trojan is run, it tries to locate an IM client's user information and to send it to a hacker via email or using the existing IM client. That way a hacker gets all data he needs to connect to an IM network using victim's credentials.

Most famous IM trojans: Ypager, Ikmet, Spy, ICQSteal.
