OS: Windows XP
Anti-Virus Software: McAfee Virus Scan version 13.15

I clicked a link on a site and McAfee detected a Trojan was being downloaded. It proceeded to quarantine what it could. However there is one file that it cannot "fix", it always recomends scanning after rebooting.

The file is:

c:\windows\system32\konayowi.dll

Some of my symptoms include pop-up ads and redirection when performing searches.


Any help on removing this is greatly appreciated!

Hello and welcome to Bleeping Computer.

Please subscribe to your topic so that you will be notified as soon as I post a reply, instead of you having to check the topic all of the time. This will allow you to get an email notification when I reply.

Lets take a look with Malwarebytes

Please download Malwarebytes' Anti-Malware from here:
Malwarebytes
Please rename the file BEFORE downloading to zztoy.exe instead of mbam-setup.exe

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.

Double Click zztoy.exe to install the application.
* Make 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.
* The scan may take some time to finish,so please be patient.
* When the scan is complete, click OK, then Show Results to view the results.
* Make sure that everything is checked, and click Remove Selected.
* When disinfection is completed, a log will open in Notepad and you may be prompted to Restart.(See Extra Note)
* The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
* Copy&Paste the entire MBAM report (even if it does not find anything) in your next reply

Extra Note:
If MBAM encounters a file that is difficult to remove,you will be presented with 1 of 2 prompts,click OK to either and let MBAM proceed with the disinfection process, if asked to restart the computer, please do so immediately.


If Malwarebytes won't install or run

Some types of malware will disable MBAM and other security tools. If MBAM will not install, try renaming it. Right-click on the mbam-setup.exe file and change the .exe extension to .bat, .com, .pif, or .scr and then double-click on it to run.

If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files, right-click on mbam.exe and change the .exe as noted above. Then double-click on it to run.

I saved the MBAM install file as zztoy.exe. I went through the install process and reached the screen that allows me to check for updates and to launch MBAM after installation was finished. I check both and click Finish. An error message appears saying it cannot execute mbam.exe. I go to that directory and it is not there.

Ok, lets try SAS:

Please run ATF and SAS:

Note.. SAS doesn't open the registry hives for other user accounts on the system, so scans should be done from each user account.

Note 2: 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 Edition

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.



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.

We'll take care of those popups after this next scan.

http://www.malwarebytes.org/mbam-clean.exe

-Please download and run that.
-Reboot after it has ran
-Try to install Malwarebytes again and run a scan.

Let's update your Internet Explorer version to 8 because it is faster and more secure. I also recommend when it asks for you to make Internet Explorer the default browser, that you do so.

You can download the new version from here:

Internet Explorer 8

Let me know once you have done this.

Please make sure that you have the SmartScreen filter enabled. You can do this by going to Safety->SmartScreen Filter-> Turn ON the SmartScreen filter.

And then after that:

Create a new Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been 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.
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.
