A remote administration utility (RAT) that allows a user to access and control a computer, usually remotely over a network or the Internet.
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 Positive. In most cases, a False Positive is fixed in a subsequent database release.
Usually, updating your F-Secure security product to use the latest database is enough to resolve the issue. You can check by first updating your F-Secure security product to use the latest detection database updates, then rescanning the file.
After checking, if you still believe the file is incorrectly detected, you can submit a sample of it to F-Secure Labs for re-analysis.
NOTE If the file was moved to quarantine, you will need to first collect the file from quarantine before you can submit it.
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.

Backdoor programs may be legitimate, and may be used for legitimate reasons by authorized administrators, but they are also frequently used by attackers to gain control of a user's machine without their knowledge or authorization.
A typical backdoor consists of 2 components - the server program, which can be installed on multiple computers, and the client program that can be used to control one or all the servers.
Attackers can distribute copies of the server program to potential victims in numerous ways - for example, as part of the payload for a worm or trojan; as a disguised file attached to a spam email; as a file shared on peer-to-peer (P2P) networks, and so on.
Attackers typically rely on either social engineering or exploiting a vulnerability to install the backdoor on a computer. Once the server program is installed, it will open a network port and communicate with the client program. An attacker can then use the client to issue commands to the machine.
A backdoor is usually able to gain control of a system because it exploits undocumented processes or features in an operating system or installed program. Depending on how sophisticated a backdoor program is, it can perform actions such as:
and so on.
