Under Attack from Trojan Bankerfox.A?

[1two3]

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.
