Backdoor.Misdat is a type of a Trojan horse that allows a third party to access and control the compromised computer without the user's knowledge and consent. It is hard to tell exactly when Backdoor.Misdat arrives at the target system, since it does not warn about the oncoming installation, and what is more, the Trojan does not have an interface so it does not pop up into your face like a rogue, for example.
However, during the installation it drops a file called msdtc.exe into the Common files folder within the Program Files directory, and seeing that msdtc.exe is a process file you are bound to find it running in Task Manager. Therefore, although there are no definite infection symptoms (that is, they might vary from a system to a system), you can determine the infection from this process file. However, do not confuse it with the legitimate msdtc.exe file that belongs to Microsoft Distributed Transaction Coordinator. The way to tell legitimate and fake files apart is checking their location - if the file is not distributed by Microsoft, and its in C:\Windows or C:\Windows\System32 directory then you surely have Backdoor.Misdat in your system.
Depending on what the hacker behind this Trojan wants it do to, Backdoor.Misdat can perform a whole list of malicious actions. Usually it lowers down the security levels of the system in order for other programs to access your computer. However, apart from opening your system for other malware, Backdoor.Misdat can also download and execute undesirable files, thus installing malicious programs on its own. Also, it can make use of the network to spread to the other computers - modified system settings allows Backdoor.Misdat that. And, probably, the most frustrating ability of this Trojan is logging of the keystrokes in order to steal sensitive personal information. So, Backdoor.Misdat does not only allow other malware into your system, it also trespasses your privacy and steals such data as banking logins, passwords, credit card numbers and so on.
Although it is possible to remove Backdoor.Misdat on your own, if you are not a computer expert, it would be better to leave the Trojan removal to the experts - get yourself a trustworthy antimalware application, run it, and wait for it to erase Backdoor.Misdat automatically for you. It is simple as that. You just have to respond immediately and do not wait until Backdoor.Misdat and the malware it brings take over your system.
