I have been living with this error long enough:
svhost.exe – Application Error
the instruction at “0x7c919af2” referenced memory at “0x00000010”, the memory could not be written
Click on OK to terminate the program
Click on CANCEL to debug the program

It pops up every single time I boot up and it's annoying. I have tried everything I know to get rid of it and it does not work. I need your invaluable help again. You guys have saved my ass many times in the past and I do appreciate all your help.

The 'puter:
Dell Inspiron 530
Intel Duo Core CPU E655
2.33GHz
2 G RAM
Windows XP Home Edition
version 2002
SP3

Thank you in advance. Peace,
Fernando

Hello,

And welcome to BleepingComputer.com, before we can assist you with your question of: Am I infected? You will need to perform the following tasks and post the logs of each if you can.

Malwarebytes Anti-Malware

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 Full 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.


SUPERAntiSpyware:

Please download and scan with SUPERAntiSpyware Free

  • Double-click SUPERAntiSypware.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 it will not start, go to Start > All Prgrams > SUPERAntiSpyware and click on Alternate Start.
  • 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 here. Double-click on the hyperlink for Download Installer 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 "General and Startup" tab, and under Start-up Options, make sure "Start SUPERAntiSpyware when Windows starts" box is unchecked.
  • Click the "Scanning Control" tab, and 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 a scan just yet.
Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with SUPERAntiSpyware as follows:
  • Launch the program and 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 and click "Next".
  • 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" 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.
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.

Now GMER

GMER does not work in 64bit Mode!!!!!!

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 Full 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.
-- If you encounter any problems, try running GMER in safe mode.
-- If GMER crashes or keeps resulting in a BSODs, uncheck Devices on the right side before scanning

OK, I ran SAS in regular mode and it scanned. Then I downloaded Gmer as per instructions, from both mirrors, and both times when I double clicked on it the blue screen popped up saying that windows shut down, message: BAD_POOL_HEADER, and procedeed to dump the physical memory. I already can't boot in safe mode, so, now what?
Peace,
Fernando

We need to know more about your BSODs...

Download BlueScreenView (in Zip file)

No installation required.

Unzip downloaded file and double click on BlueScreenView.exe file to run the program and When scanning is done, go to Edit > Select All.

Then go to File > Save Selected Items, and save the report as BSOD.txt.

Open BSOD.txt in Notepad, copy all content, and paste it into your next reply.

Compliments of Broni

Out of curiosity, have you tried simply disabling it from starting up with Windows via MSConfig? In my case, svhost.exe was a virus, and from Googling it, it seems that's what it is (as opposed to the proper svchost.exe). I'm not knowledgable about these matters though (perhaps you should wait for someone to confirm what I said before trying it), but it certaintly fixed my problems. On my system, it re-wrote certain things in the registry, so I am guessing that's what it's trying (but failing) to do in your case.

It is a typo, sorry. I went into MSCONFIG anyway and there's no sign of the svhost.exe file.
Thank you all for your help. Performing BSOD duties now. Peace
