Last night I (stupidly) downloaded what I believed to be a firefox update and ran the program. Unfortunately it turned out to be a trojan and I can't seem to get rid of it. Nothing too bad has happened to the computer yet but warnings keep popping up from AVG telling me there has been a trojan found. These are the descriptions from AVG.

Trojan horse Generic19.AKTW
Trojan horse Agent2.BODZ

So far I have performed 2 AVG scans and an ESET online scan.

The AVG scan today found 2 infections, but then during the ESET scan more infections were popping up on AVG.
The ESET scan found nothing.

I thought I'd better check with the experts before I do anything, in case I make things worse.
What should I do next?

Many thanks in advance.

I did exactly the same thing and got the Trojan virus!! I cannot remove infected file as I fear removing this windows system file which will more than likely cause inability to reboot - I am stuck here!!

The named file (infected) and stored in my C:/WINDOWS folder is named:

Wdikya.exe

File info:

Description: GoldG
Company: Simon Tatham
File version: 3.1.1.1

Sounds good. It always helps to see all logs so we know what we are / were dealing with.
The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.

Good,no Kazy file,,, Now we need a safe mode scan.. Hopefuly we'll be good after this.

Next run ATF and SAS: If you cannot access Safe Mode,run in normal ,but let me know.

Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

From your regular user account..
Download Attribune's ATF Cleaner and then SUPERAntiSpyware , Free Home Version. Save both to desktop ..
DO NOT run yet.
Open SUPER from icon and install and Update it
Under Scanner Options make sure the following are checked (leave all others unchecked):
Close browsers before scanning.
Scan for tracking cookies.
Terminate memory threats before quarantining
.
Click the "Close" button to leave the control center screen and exit the program. DO NOT run yet.

Now reboot into Safe Mode: How to enter safe mode(XP)
Using the F8 Method
Restart your computer.
When the machine first starts again it will generally list some equipment that is installed in your machine, amount of memory, hard drives installed etc. At this point you should gently tap the F8 key repeatedly until you are presented with a Windows XP Advanced Options menu.
Select the option for Safe Mode using the arrow keys.
Then press enter on your keyboard to boot into Safe Mode
.

Double-click ATF-Cleaner.exe to run the program.
Under Main "Select Files to Delete" choose: Select All.
Click the Empty Selected button.

If you use Firefox or Opera browser click that browser at the top and choose: Select All
Click the Empty Selected button.
If you would like to keep your saved passwords, please click No at the prompt.
Click Exit on the Main menu to close the program
.

NOW Scan with SUPER
Open from the desktop icon or the program Files list
On the left, make sure you check C:\Fixed Drive.
Perform a Complete scan. After scan,Verify they are all checked.
Click OK on the summary screen to quarantine all found items.
If asked if you want to reboot, click "Yes" and reboot normally.

To retrieve the removal information after reboot, launch SUPERAntispyware again.
Click Preferences, then click the Statistics/Logs tab.
Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
If there are several logs, click the current dated log and press View log.
A text file will open in your default text editor.
Please copy and paste the Scan Log results in your next reply.
Click Close to exit the program.



Rerun MBAM (MalwareBytes) like this:

Open MBAM in normal/regular mode and click Update tab, select Check for Updates,when done
click Scanner tab,select Quick scan and scan (normal mode).
After scan click Remove Selected, Post new scan log and Reboot into normal mode.


Please ask any needed questions,post logs and Let us know how the PC is running now.

OK, I just finished the Super scan, but I can't find the log. I've looked where you said it should be but it's not there. The only results that came up were 100+ tracking cookies. It may be that because I ran the scan as the administrator it's not showing the log in my usual user mode? I'll try logging on as the administrator in safe mode and see if I can retrieve the log.
I've run out of time now, I'll have to finish up tomorrow.

Thanks :thumbsup:

Sometimes this happens and it comes back after a shut down and reboot. Also it sometimes shows up in the Admin or other user account. If it only found cookies,we really don't need to see it.

Run the MBAM scan as we look good. How is it running?

Excellent!! Now you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been backed up, renamed and saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Vista and Windows 7 users can refer to these links: Create a New Restore Point in Vista or Windows 7 and Disk Cleanup in Vista.
