Getting rid of Trojan/Backdoor help
well, I have a bit of a problem, it seems my g/f's computer has either a trojan or a back door on it and I have no idea how to get rid of it. I found out because her internet provider sent her an e-mail saying her computer was sending lots of spam e-mails I believe. Anyway, I tried using smackit and AVG to get rid of it but neither worked, at least I don't think they did. AVG did get rid of a virus but now about every 5 seconds an error box pops up saying that AVG had detected trojan BackDoor.Afcore.AI in file Windows\system32:bnweswh.dll. Anyway, it is a huge pain in the ass and I need to get rid of it or her internet provider is going to shut off her internet. Any help would be extremely grateful.
ps. I did a search for something like this but couldn't find anything, sorry if this has been covered somewhere else before

Go here for the cleaner from Moosoft and down load the Cleaner (it has a 30 day free trial). Run it, and it should cure your g/f's problem.

Afcore is a backdoor Trojan program that appears as a Windows application file (.dll file) with a size of about 110KB. The Trojan has numerous functions that give 'evildoers' almost full control of victim computers.
Infected message body text contains the following:
If you read this, then this program was probably stolen from our laboratory. Author of this software is not responsible for any harm that may be caused by incompetent or malicious persons who use this software possibly running on your machine. Therefore, please remove this software as soon as possible. Click the "Start" menu, select "Run", enter there: rundll32 ,Uninstall and click "OK"
Upon being launched (executed) the backdoor program installs itself into the supplemental file stream of the NTFS that is associated with the system32 catalog system.
The backdoor registers itself into the system registry auto run key:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run (assigned name) =
rundll32 (path to the backdoor program),(options)
The file name is formed from a combination of arbitrary symbols.
The backdoor program has several options that it can use:
To remotely uninstall itself from victim machines the backdoor uses the following command:
rundll32 ÄÉÓË:\%windir%\system32:(name of the backdoor.dll file),Uninstall
When the uninstall command is sent, the afcore virus uninstalls itself from the system registry and remaining only in the file stream and is no longer managed by the start system. To remove the afcore backdoor program from the file stream it is necessary to use a special utility.
from a french message board:
try to type in a console
rundll32 c:\\%windir%\\system32:(nom of the file dll), Uninstall then erases the file.
clean the base of the register the key is
HKLM\\Software\\Microsoft\\Windows\\CurrentVersion\\Run (nomdela DLL) =
rundll32 (emplacementdela dll), (options)

A few thoughts for you:
1. Run your AV and spy/ad/trojan/bot killers in safe mode
2. Go to http://www.diamondcs.com.au and get the trial versions of their spy/bot/trojan/worm killers. Also get Registry Prot, but do not install this until your machine is clean.
3. Go to http://www.winpatrol.com and get WinPatrol
4. Go to http://www.swatit.org and get SwatIT v2.1
5. Go to http://vil.nai.com/vil/stinger and get Stinger
6. Go to http://www.spywareinfo.com/~merijn/index.html and get Hijack This ....Be careful, it shows ALL running proceses, not just bad ones.
7. Go to http://www.wilderssecurity.net and getSpyware Blaster and Spyware Guard
8. Go to http://www.sysinternals.com and get Mail Control. This will stop the spamming going out.
As you have been "owned", the only safe way to be sure that you are clean is to reformat your hard drive an re-install all your software, as you do not know what else might have been put on your machine?
Hope this helps
