Backdoor.win32.Bifrose.aej HELP!!

I am running Windows Vista on an Asus g2s-a1 laptop.
World of Warcraft is telling me that it has detected the trojan Backdoor.win32.bifrose.aej
NO scanners or antivirus programs have detected it or located it.
I have spent the past 3 hours googling and researching online everything I can about it. I’ve come up with nearly squat.
No advice, no suggestions, and no ‘past fixes’ have worked or have been any help.

I desperately need some help on getting rid of this trojan. I have done everything!

What is your firewall ?

I would probably be a little suspect of World of Warcraft reporting a backdor trojan, how can it tell what is on your system ?
Have you visited the WoW forum to see if others are suffering similar issues.

In the meantime you could check with some anti-spyware tools.
If you haven’t already got this software (freeware), download, install, update and run it, preferably in safe mode.
AVG anti-spyware (formerly Ewido). Or SUPERantispyware Or Spyware Terminator.

Online games now scan for malware: both game cheats and password stealing Trojans.

When I say that I’ve come up with nearly squat, it means that what I did find did not work. Neither of the ‘answers’ in those links worked. None of them did, and there’s been a lot.

Have you run the other anti-spyware options given ?

If no AV scanner is detecting it, then it must be a new variant.

Your options are to have a look for suspicious files, possibly in the location mentioned in the forum post I found previously:

I have found a copy of this backdoor keylogger. There is only one varation on this backdoor which is an executable file placed inside C:/Program Files/ and is named "howtodo.exe".]I have found a copy of this backdoor keylogger.

You can submit any suspicious files to VirusTotal for analysis.

Your next option is to contact the World of Warcraft technical support people: they seem eager to help you:

Also, I have found this NvScv. I am very sure it is a trojan because that’s what googling it says. I don’t know how best to get rid of it, though!

Nevermind! It’s NvSvc, which apparently could either be a trojan or an nVidia thing.

How is the best way to get rid of it? And I am equally suspicious because I have not installed MSN on this machine. And it is showing the words Bifrose, which is a very key word in my trojan!

Should I give you another HijackThis log? I disabled the hidden files like you asked.

Run HijjackThis! again, tick the box next to this entry and click ‘fix’:

Reboot and delete the file.

And/or try the Bitdefender scanner:

IT WORKED!

Thank you so much, FreewheelinFrank! Your advice was very helpful and it WORKED. I now know what to do and who to come to if something like this happens again :slight_smile:

You rock!

And where to come…
