I'm a new user, and after navigating all the instructions I hope I'm posting correctly.

My laptop is running Windows XP and has picked up some kind of virus. I believe I had neglected to update my flash player, (I had seen a prompt over the last couple weeks when i started up from Adobe, but stupidly clicked "remind later" a few times) and when I went to a website I got a message saying I needed to update, but when I did I got what was probably a bogus download/executable file. Since then, I've had a few problems:
1. I use Firefox, but IE opens when I start up; (I can still get to Firefox, but have to close IE - which I never use)
2. Microsoft Security Essentials has disappeared from the lower toolbar, and when I try to launch from all programs it won't open;
3. If I try to search for something like My Bleeping Computer I get redirected to bogus sites;
4. There are a couple of odd things on my task manager - one called drx.exe and one called dsyboa.exe

I have gotten viruses in the past and used this site (removal instructions) including the rkill process to remove them. But this is a slower (or more insidious) virus that doesn't flash warnings etc., and allows the computer to mostly function other than the points above. I don't see anything on this site about those files (drx and dsyboa).

What can I do?

Hi wreckscarnage,

:welcome: to BleepingComputer! Sorry for the delay.

:step1: Let's try rebooting into Safe Mode.
This can be done tapping the F8 key as soon as you start your computer
You will be brought to a menu with several options. Press the down arrow key on your keyboard until Safe Mode with Networking is selected. Press Enter. Please see here for additional details.

:step2: Once in Safe Mode with Networking, download Rkill (renamed iExplore.exe)

Run Rkill (renamed iExplore.exe).

If you are unable to download rkill from the main download, try these alternate download locations:

1. http://download.bleepingcomputer.com/grinler/rkill.com
2. http://download.bleepingcomputer.com/grinler/rkill.pif
3. http://download.bleepingcomputer.com/grinler/rkill.scr
4. http://download.bleepingcomputer.com/grinler/eXplorer.exe
5. http://download.bleepingcomputer.com/grinler/iExplore.exe
6. http://download.bleepingcomputer.com/grinler/uSeRiNiT.exe
7. http://download.bleepingcomputer.com/grinler/WiNlOgOn.exe
8. http://www.boredomsoft.org/hosted/rkill.exe
9. http://www.boredomsoft.org/hosted/rkill.com
10. http://www.boredomsoft.org/hosted/rkill.scr
11. http://www.boredomsoft.org/hosted/eXplorer.exe
12. http://www.boredomsoft.org/hosted/iExplore.exe


Please be patient while Rkill looks for various malware programs and ends them. When it has finished, the black window will automatically close and you can continue with the next step. If it appears like Rkill did not stop the malware from running, please try running RKill again until the malware is no longer running.

Do not reboot your computer after running RKill as the malware programs will start again!


:step3: Still in Safe Mode with Networking, Please download Malwarebytes Anti-Malware and save it to your desktop.
Download Link 1
Download Link 2MBAM 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.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
    For instructions with screenshots, please refer to the How to use Malwarebytes' Anti-Malware Guide.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • 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.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Troubleshoot Malwarebytes' Anti-Malware


:step4: Reboot into Normal mode. Next run Superantisypware (SAS):

Download and scan with SUPERAntiSpyware Free for Home Users
  • Double-click SUPERAntiSpyware.exe and use the default settings for installation.
  • An icon will be created on your desktop. Double-click that icon to launch the program.
  • If asked to update the program definitions, click "Yes". If not, update the definitions before scanning by selecting "Check for Updates". (If you encounter any problems while downloading the updates, manually download them from http://www.superantispyware.com/downloads/SASDEFINITIONS.EXE (copy and paste that website address) and save SASDEFINITIONS.EXE to your desktop. Then double-click on SASDEFINITIONS.EXE to install the definitions.)
  • In the Main Menu, click the Preferences... button.
  • Click the Scanning Control tab.
  • 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.
  • Back on the main screen, under "Scan for Harmful Software" click Scan your computer.
  • On the left, make sure you check C:\Fixed Drive.
  • On the right, under "Complete Scan", choose Perform Complete Scan.
  • Click "Next" to start the scan. Please be patient while it scans your computer.
  • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
  • Make sure everything has a checkmark next to it and click "Next".
  • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
  • If asked if you want to reboot, click "Yes".
  • 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.
If you have a problem downloading, installing or getting SAS to run, try downloading and using the SUPERAntiSpyware Portable Scanner instead. Save the randomly named file (i.e. SAS_1710895.COM) to a usb drive or CD and transfer to the infected computer. Then double-click on it to launch and scan. The file is randomly named to help keep malware from blocking the scanner.

In your next reply, please include:
  • Malwarebytes' log file
  • SUPERAntiSpyware log file
  • How's the computer running now? Please include a detailed description of anything out of the ordinary.

I have good news and bad news. The good news is, strange boxes saying dsyboa could not run have stopped, and dsyboa and drx no longer show up as strange processes on the task manager. The bad news is, Google is still redirecting when I click on items identified in a search, and I still can't get Microsoft Security Essentials to open, or to show up at the bottom of my screen. the computer otherwise seems to be operating fairly normally. I assume this means that I have to run some other fixes to get rid of a hidden redirecting virus, right?

Hi wreckscarnage,

Sorry for the delay. Yes, let's try and fix the redirecting.

:step1: Download Security Check by screen317 from here.
  • Save it to your Desktop.
  • Double click SecurityCheck.exe and follow the onscreen instructions inside of the black box.
  • A Notepad document should open automatically called checkup.txt.
  • Please post the contents of that document.


:step2: Please download MiniToolBox by Farbar and run it.
Checkmark following boxes:
  • Report IE Proxy Settings
  • List content of Hosts
  • List IP configuration
  • List last 10 Event Viewer log
  • List Users, Partitions and Memory size
Click Go and post the result.


:step3: Please follow our Removal Guide here How to remove Google Redirects. You will move to the Automated Removal Instructions

If it finds something make sure Cure is selected
Next click Continue then Reboot now
A log file should be created on your C: drive named "TDSSKiller.txt" please copy and paste the contents in your next reply.


:step4: Rerun Malwarebytes in Normal Mode
Open Malwarebytes and click on the Update tab, then click on the Check for Updates button.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • 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.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Troubleshoot Malwarebytes' Anti-Malware

:step5: Please download GMER from one of the following locations and save it to your desktop:
  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.

    Posted Image
  • GMER will open to the Rootkit/Malware tab and perform an automatic quick scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.

IMPORTANT! If for some reason GMER refuses to run, try again.
If it still fails, try to UN-check "Devices" in right pane.
If still no joy, try to run it from Safe Mode.


In your next reply, please include:
  • SecurityCheck's checkup.txt file
  • MiniToolbox's Result.txt file
  • Malwarebytes' log file
  • TDSSKiller log
  • GMER log file
  • How's the computer running now? Are you still redirecting? Does Microsoft Security Essentials open? Please describe in detail anything else out of the ordinary.
