Greetings,
It's been on my comp for about 4 days now, each day allows less access to programs, etc than the last. Through my search online this seems to be popular malware that may require combofix or something similar (hopefully not?). I tried to search it within this forum but didn't find it (please direct me if this has already been dealt with).


About the Virus: A constant message pops up as an svchost.exe application error saying:

The instruction at 0x75606e6a referenced memory at 0x0000008, memory could not be "read" click ok to terminate the program.

Symptoms: Loss of internet access, loss of sound, inability to use virus scan program, inability to access Safe Mode...

Assistance for this issue would be greatly appreciated!
Much thanks in advance.

Hello ncsaavy and welcome to BC :thumbsup:

As no logs have been posted, I am shifting this topic from the specialized HiJack This forum to the Am I Infected forum.

PLEASE DO NOT NOW POST LOGS unless a log is specifically requested.

What is your operating system: Windows XP, Vista, etc.?

What security programs do you have installed?

Hi, i 'll tell right up, this probably won't end well and you will need to reformat. Do you have a way to back up important files?

Please download Malwarebytes Anti-Malware (v1.32) and save it to your desktop.
alternate download link 1
alternate download link 2
If you have a previous version of MBAM, remove it via Add/Remove Programs and download a fresh copy.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • 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 updates, manually download them from here and just double-click on mbam-rules.exe to install. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.
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 and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. 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 after scanning with MBAM. Please temporarily disable such programs or permit them to allow the changes.


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..


***
Another work around is by not using the mouse to install it, Just use the arrow keys, tab, and enter keys.
***
Open up command prompt, type in following commands:
XP >> click the Start menu at the lower-left of your computer's desktop and select "Run". Type cmd into the Run box and click "OK".
Vista >> click the Start menu at the lower-left of your computer's desktop and Type cmd in the search box.

regsvr32 mbamext.dll
regsvr32 ssubtmr6.dll
regsvr32 vbalsgrid6.ocx
regsvr32 zlib.dll

****

If you cannot use the Internet,you will need access to another computer that has a connection.
From there save mbam-setup.exe to a flash,usb,jump drive or CD. Now transfer it to the infected machine, then install and run the program.
If you cannot transfer to or install on the infected machine, try running the setup (installation) file directly from the flash drive or CD by double-clicking on mbam-setup.exe so it will install on the hard drive.

Manually Downloading Updates:
Manually download them from HERE and just double-click on mbam-rules.exe to install. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.

***
Try using a System Retore Point prior to the date of infection. You may be able to update and run MBam. Note this did not remove the malware.

Greetings boopme and orange blossom,

Thanks for the reply and help with this issue.

I am currently stuck at attempting to run malware bytes. The nature of this virus won't let me run it. I tried all the suggestion for alternative ways to run malware bytes, and I am not able to run system restore - Any other suggestions?

On the positive, I have back access to the net and sound, also safe mode works. But still cannot open/run any programs, esp norton antivirus or malware bytes- and the error message continues to pop up.

Thanks

ncsaavy

Greetings boopme,
Thanks for your reply.
As mentioned earlier, I tried all of these (below) and none of them work. Anything else I can do?

Sorry I lost you. if these won't run then,We need to run HJT/DDS.
Please follow this guide. go and do steps 6 and 7 ,, Preparation Guide For Use Before Using Hijackthis. Then go here HijackThis Logs and Virus/Trojan/Spyware/Malware Removal ,click New Topic,give it a relevant Title and post that complete log.

If you cannot get DDS to work, please try this instead.

Please download RSIT by random/random and save it to your Desktop.
Note: You will need to run this tool while connected to the Internet so it can download HijackThis if it is not located on your system. If you get a warning from your firewall or other security programs regarding Rist attempting to contact the Internet, please allow the connection.
  • Close all applications and windows so that you have nothing open and are at your Desktop.
  • Double-click on RSIT.exe to start the program.
  • If using Windows Vista, be sure to Run As Administrator.
  • Click Continue after reading the disclaimer screen.
  • Leave the drop down box set to default: "List/folders created or modified in the last 1 month (30 days).
  • When the scan is complete, a text file named log.txt will automatically open in Notepad.
  • Save the log file to your desktop and copy/paste the contents into a new topic in the HijackThis Logs and Malware Removal forum, NOT here.
Important: Be sure to mention that you tried to follow the Prep Guide but were unable to get DDS to run.
If RSIT did not work, then reply back here.


Let me know if it went OK.

Ok,that looks good.
Now that your log is properly posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a HJT Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the HJT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the HJT Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.

To avoid confusion, I am closing this topic.
