Title: Under Attack from Trojan Bankerfox.A?
Post by: 1two3 on August 04, 2010, 01:53:11 PM
My laptop is screwed. I'm on my other computer now that I never use for anything but email etc, so this one is safe. My laptop is Windows 7 Ultimate. Running Avast free (latest version)

I started having a fake AV (Antivir), getting messages telling me that:

 "Application cannot be executed. The file ("sf.bin" or "wltuser.exe") is infected. Do you want to activate your antivirus software now?"

It tries to open up www.*censored*.com on IE (I don't watch porn)

I get, in the bottom right corner, a message telling me that:

Your computer is being attacked by an internet virus. It could be a password-stealing attack, a trojan - dropper or similar.

Details:
Attack from (random ip, random port)
Attacked port (usually 49593)
Threat:  ("Bankerfox.A", or "wsqmcons.xe", or "waucult.exe". Sometimes "win32/Nuqel.e" or something.
(I'm sure it's the fake AV telling me, because it doesn't look like Windows or Avast at all.



I can't open any webpage from Firefox or IE. Tells me that there is a virus warning and to buy some software. If I try to open Chrome, it tells me it can't. It automatically opens IE every few minutes. I think it's going to some webpage but I don't know what as I close it down before it does.


Please help, I've no idea what to do. Scanning with Avast buy it doesn't seem to be doing anything. If you can't help, I'll have to take it into a specialist.

Replying as it won't let me edit anymore.

For some reason, when I noted up my laptop today, avast blocked the Trojan so there was no Antivir or alerts. I've removed the proxies that Antivir put on IE and Firefox, but I'm not using the computer for anything yet as I want to know if the Trojan is actually gone. If you could still help it would be great thanks.

Hello and welcome to Computer Hope Forum. My name is Dave. I will be helping you out with your particular problem on your computer. I am working under the guidance of one of the specialist of this forum so it may take a bit longer to process your logs.

1. I will be working on your Malware issues. This may or may not solve other issues you have with your machine.
2. The fixes are specific to your problem and should only be used for this issue on this machine.
3. If you don't know or understand something, please don't hesitate to ask.
4. Please DO NOT run any other tools or scans while I am helping you.
5. It is important that you reply to this thread. Do not start a new topic.
6. Your security programs may give warnings for some of the tools I will ask you to use. Be assured, any links I give are safe.
7. Absence of symptoms does not mean that everything is clear.

Please download and run the below tool named Rkill (courtesy of BleepingComputer.com) which may help allow other programs to run.
Save Rkill to your desktop.

There are 4 different versions. If one of them won't run then download and try to run the other one.
 
Vista and Win7 users need to right click Rkill and choose Run as Administrator
 

You only need to get one of these to run, not all of them. You may get warnings from your antivirus about this tool, ignore them or shutdown your antivirus.

Once you've gotten one of them to run then try to immediately run the following.
