twex.exe is a variant of ZBot, which is a password and personal information stealer.

First let's flush your DNS cache, and restore MS's original Hosts file.

Copy and paste these lines in Note pad.
@Echo on
pushd\windows\system32\drivers\etc
attrib -h -s -r hosts
echo 127.0.0.1 localhost>HOSTS
attrib +r +h +s hosts
popd
ipconfig /release
ipconfig /renew
ipconfig /flushdns
netsh winsock reset all
netsh int ip reset all
shutdown -r -t 1
del %0

Save as flush.bat to your desktop. Right click on the .bat file and run as Administrator. Your computer will reboot itself.

After rebooting download Malwarebytes' Anti-Malware to your desktop
|MG| Malwarebytes Anti-Malware 1.46 Download
* Double-click mbam-setup.exe and follow the prompts to install the program.
* At the end, be sure a checkmark is placed next to 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.
* 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. Please save it to a convenient location. Copy and Paste that log into your next reply.

Malwarebytes runs with pretty much every AV program I've ever heard about with no problems (unlike many or maybe even most other programs). But make sure that Kaspersky isn't scheduled to do a scan at the same time that you run the Malwarebytes scan (it wouldn't be good to run both scans at the same time - I don't know that it would cause a problem, but let's avoid it just to be on the safe side). Keep in mind it could take a few hours for a full scan depending on the amount of data you need to scan on however many drives/partitions you need to scan. You're safe running it without disabling or uninstalling Kaspersky.

Remember, Malwarebytes is just scanning and then it can remove what it finds - it is not operating in real time to protect your system so you should definitely leave Kaspersky enabled even during the Malwarebytes scan if you intend to go online (just make sure it isn't scheduled to scan and if so, disable the scan or delay it or whatever is necessary to keep it from starting until the Malwarebytes scan is complete).

In fact, you may want to keep Malwarebytes installed and update and run Malwarebytes every few weeks or month or so just as a backup to catch anything that might have been missed. I do that myself (though my primary program is MSE). It rarely catches anything because MSE is very good, but sometimes it does and so I'm happy to have it and glad I have this good habit.

I hope this helps and that the above suggestions and Malwarebytes resolve the problem. If not, there are other options available - so don't worry, we'll get rid of this infection (and perhaps other infections not noticed at the same time). The mere fact that it has been idenfied is an excellent sign as solutions for identified variants are easier to locate and are often included in some of the more common anti-malware tools already. I suspect that may be at least one of the reasons why this product was recommended (besides the fact that it is very good in general).

Good luck!

I'm nowhere near a malware cleanup expert so I have nothing to offer here in terms of resolving the problem when someone like Jacee is already involved, but from viewing other threads on the subject, the expert often likes to see another MBAM log after the cleanup (if something was found) to confirm that nothing else is found or remains. Perhaps while waiting for Jacee, you could re-run MBAM and attach an updated log to verify how it now looks after the cleanup. I'm in no way trying to take over her job here - I'm just suggesting something to do while awaiting her reply that may assist her (and shouldn't be much trouble to do).

I hope this helps both of you.

Good luck!

Change all your passwords using a known 'clean' computer. Do not use the infected one to do this.

Please download TFC by Old Timer TFC - Temp File Cleaner by OldTimer - Geeks to Go Forums and save it to your desktop.

Save any unsaved work. TFC will close ALL open programs including your browser!
Using Vista/Windows 7 right-click on the file and choose Run As Administrator.
Click the Start button to begin the cleaning process and let it run uninterrupted to completion.

Important! If TFC prompts you to reboot, please do so immediately. If not prompted, manually reboot the machine anyway to ensure a complete clean.

TFC (Temp File Cleaner) will clear out all temp folders for all user accounts (temp, IE temp, java, FF, Opera, Chrome, Safari), including Administrator, All Users, LocalService, NetworkService, and any other accounts in the user folder. It also cleans out the %systemroot%\temp folder and checks for .tmp files in the %systemdrive% root folder, %systemroot%, and the system32 folder (both 32bit and 64bit on 64bit OSs). It shows the amount removed for each location found (in bytes) and the total removed (in MB). Before running, it will stop Explorer and all other running apps.
TFC only cleans temp folders. TFC will not clean URL history, prefetch, or cookies. Depending on how often someone cleans their temp folders, their system hardware, and how many accounts are present, it can take anywhere from a few seconds to a minute or more. TFC will completely clear all temp files where other temp file cleaners may fail.

Rescan with Malwarebytes' and post a fresh log.

OK done. Is it really necessary for me to do another full malwarebyte scan since it deleted everything it found already, just wondering.

If it was my computer with a Zbot Trojan, I'd gladly run a deep scan again!

Looks good! Now running Kaspersky, in full mode (not quick scan) report?

Let's take one more look.

Download DDS from one of these links:
Mirror 1 Mirror 2 Mirror 3
  • Disable any script blocking protection
  • Right click the dds icon to run the tool as Administrator.
  • When done, DDS will open two (2) logs:
    1. DDS.txt
    2. Attach.txt <--- this will be minimized in the task tray
  • Save both reports to your desktop.
Include the contents of both logs in your next reply.

Pcvista, why do you have a file on your computer called Keygen? Located here: C:\Users\shua\Desktop\Keygen.exe

What is it for, and why do you use it?

Viruses and malware usually do their best to hide themselves behind innocent names. You would never find a virus with a name such as "virus.exe", for obvious reasons. It is therefore fairly safe to assume that "conhost" does not relate to a con-job. AFAIK, it gets invoked by the Command Processor and "con" relates to "Console".
