hi, i really dont know a great deal about infections, rootkits etc but i believe im infected with something pretty nasty called twext.exe and i have no idea how to get rid of it, iv tried scanning with spybot but it gets disabled half way through the process, iv also tried unhackme but it finds nothing, i tried to reinstall windows but get an error message and the system restarts, i would be very thankful if someone could take a look at my hijackthis log and give me advice on removal, thank you in advance.

You should do two things:

1. download and run avast! antivirus Home Edition Free for Home Users...
from: http://www.avast.com/eng/download-avast-home.html

When you first install this free program... and it goes to reboot, it will scan your computer with an intense anti virus and trojan scan.
This should find your problem and remove it.
then use step two....

2. download and run Spybot - Search & Destroy©® 1.6.2
It is a free anti-virus program that is very effective.

from: http://www.safer-networking.org/en/download/

After installing both, I let them monitor my system. I have avoided further intrusions using this method.

I use both simultaneously, I have never had a problem since...

Not a good idea to install an AV when you already have one installed. Does your Comodo have the AV or McAfee?

==

Can you please do the following.

===============

Scan with HijackThis and then place a check next to all the following, if present:


F2 - REG:system.ini: UserInit=C:\WINDOWS\system32\userinit.exe,C:\WINDOWS\system32\twext.exe,

O3 - Toolbar: AVG Security Toolbar - {A057A204-BACC-4D26-9990-79A187E2698E} - (no file)

O20 - Winlogon Notify: WinCtrl32 - C:\WINDOWS\SYSTEM32\WinCtrl32.dll


Now, close all instances of Internet Explorer and any other windows you have open except HiJackThis, click "Fix checked".

===============

Locate and delete the following item(s), if present. Make sure you are able to view system and hidden files/ folders:

files...

C:\WINDOWS\system32\twext.exe
C:\WINDOWS\SYSTEM32\WinCtrl32.dll

-

Note that some of these file(s)/folder(s) may or may not be present. If present, and cannot be deleted because they're 'in use', try deleting them in Safe Mode by doing the following:

  • Restart your computer
  • After hearing your computer beep once during startup, but before the Windows icon appears, press F8.
  • Instead of Windows loading as normal, a menu should appear.

Select the first option to run Windows in Safe Mode hit enter.

-

Reboot.

===============

Download Malwarebytes' Anti-Malware (http://www.majorgeeks.com/Malwarebytes_Anti-Malware_d5756.html) to your desktop.

* At the end, be sure to checkmark the Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
* If an update is found, it will download and install the latest version.
* Download the update from here if you have problems.
* Once the program has loaded, select Perform full scan, then click Scan.
* When the scan is complete, click OK, then Show Results to view the results.
* Be sure that everything is checked, and click Remove Selected.
* When completed, a log will open in Notepad.
* Post the log back here.

The log can also be found here:
C:\Documents and Settings\Username\Application Data\Malwarebytes\Malwarebytes' Anti-Malware\Logs\log-date.txt
Or at C:\Program Files\Malwarebytes' Anti-Malware\Logs\log-date.txt

Make sure that you restart the computer.

Post new HJT log.

hi thank you for replying, ok i ran spybot found nothing, avast also found nothing, ran hijackthis and deleted the items most of them deleted however
F2 - REG:system.ini: UserInit=C:\WINDOWS\system32\userinit.exe,C:\WINDOWS\system32\twext.exe, seems to jus add itself as soon as i scan again as does
O20 - Winlogon Notify: WinCtrl32 - C:\WINDOWS\SYSTEM32\WinCtrl32.dll

tried deleting both twext.exe and winctrl32.exe in safe mode but twext.exe jus respawns after a few seconds and winctrl32.exe says "in use".
did a scan with root kit revealer and found some pretty suspicious looking things under the names of twain.exe and twain.dll niether of these will delete in the windows folder.
cannot update Malwarebytes as whats ever eating my pc will not allow me to go online so im using my laptop.
i will post a fresh hijack this log later today. cheers

Please download ComboFix by sUBs from HERE or HERE

  • You must download it to and run it from your Desktop
  • Physically disconnect from the internet.
  • Now STOP all your monitoring programs (Antivirus/Antispyware, Guards and Shields) as they could easily interfere with ComboFix.
  • Double click combofix.exe & follow the prompts.
  • When finished, it will produce a log. Please save that log to post in your next reply along with a fresh HJT log
  • Re-enable all the programs that were disabled during the running of ComboFix..

Note:
Do not mouse-click combofix's window while it is running. That may cause it to stall.

CF disconnects your machine from the internet. The connection is automatically restored before CF completes its run. If CF runs into difficulty and terminates prematurely, the connection can be manually restored by restarting your machine.

Run Combofix ONCE only!!

combofix sorted it, pc back up and running smooth, thanx alot guys. appretiate it :)

No worries, but we ask for the logs for a reason. There are also steps to be done in combofix to finish off otherwise I would have written one line. " Run Combofix."

Crunchie, Very Nice, I guess he had a root kit infection...great work
