    I guess your computer is infected with this trojan.
    See here for which AV vendors got this in their definitions.

    Also try scanning this file at VirusTotal , and hopefully more AV vendors will add detection for it soon.

    Hi kjempen

    Thanks for the link, its similar to jotti.org link. So, you think my comp is infected, and that is exactly what I mean, assuming that my comp is infected, what is the use of NOD32, adaware, spybot S&D, spywareguard, spywareblaster and M$ antispyware if they cant detect the infection. Which scanner is reliable then. thanks

    Yes, it is similar to jotti, but it does have a few scanners that jotti doesn't.
    Also, when you scan files at these 2 places you also submit the samples that are scanned automatically in the same process.

    No scanner can protect you 100%. It is not a bad selection you have of security programs, but might I suggest something like NOD32 combined with Trojan Defence Suite 3? And do you have a firewall? Firewalls are extremely important when it comes to protection for backdoor trojans.

    You seemed to be extremely unlucky since you came across a piece of malware that even KAV failed to detect (which usually have a signature for almost every piece of malware out there).

    Good luck! And don't give up just because you got unlucky one time.

    EDIT: Some stupid typos etc. fixed
