scvhost.exe malware

[ian3]

Hi Elise,

I was wondering if you would be kind enough to fix a scvhost.exe problem that seems very similar to the one you helped Alfred with in this thread (http://forums.malwarebytes.org/index.php?showtopic=61035&pid=305653&mode=threaded&start=)

I have all the present symptoms as Alfred did initially, along with my computer freezing when left to idle.

If you can help me, that would be much appreciated!

Thanks

Ian

Hi, how are things running now?

UPDATE JAVA

------------------

Your version of Java is out of date. Older versions have vulnerabilities that malicious sites can use to exploit and infect your system. Please follow these steps to remove older version Java components and update:

• Download the latest version of Java Runtime Environment (JRE) Version 6 and save it to your desktop.
  
• Look for "JDK 6 Update 21 (JDK or JRE)".
  
• Click the "Download JRE" button to the right.
  
• Select your Platform: "Windows".
  
• Select your Language: "Multi-language".
  
• Read the License Agreement, and then check the box that says: "Accept License Agreement".
  
• Click Continue and the page will refresh.
  
• Under Required Files, check the box for Windows Offline Installation, click the link below it and save the file to your desktop.
  
• Close any programs you may have running - especially your web browser.
  

Go to Start > Settings > Control Panel, double-click on Add/Remove Programs and remove all older versions of Java.

• Check (highlight) any item with Java Runtime Environment (JRE or J2SE) in the name.
  
• Click the Remove or Change/Remove button and follow the onscreen instructions for the Java uninstaller.
  
• Repeat as many times as necessary to remove each Java versions.
  
• Reboot your computer once all Java components are removed.
  
• Then from your desktop double-click on jre-6u21-windows-i586.exe to install the newest version.
  
• If using Windows Vista and the installer refuses to launch due to insufficient user permissions, then Run As Administrator.
  
• When the Java Setup - Welcome window opens, click the Install > button.
  
• If offered to install a Toolbar, just uncheck the box before continuing unless you want it.
  

-- Starting with Java 6u10, the uninstaller incorporated in each new release uses Enhanced Auto update to automatically remove the previous version when updating to a later update release. It will not remove older versions, so they will need to be removed manually.

-- Java is updated frequently. If you want to be automatically notified of future updates, just turn on the Java Automatic Update feature and you will not have to remember to update when Java releases a new version.

Note: The Java Quick Starter (JQS.exe) adds a service to improve the initial startup time of Java applets and applications. To disable the JQS service if you don't want to use it, go to Start > Control Panel > Java > Advanced > Miscellaneous and uncheck the box for Java Quick Starter. Click Ok and reboot your computer.

MALWAREBYTES ANTIMALWARE

Please launch MBAM and 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.

• 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.

Hi Elise,

I have scanned with MalwareBytes and here are the logs. They are in two separate files because I did two drives first and then did the last one. The scan says that there isn't anything found.

Weird thing is it doesn't seem like it has gotten better. My computer still freezes after about 20-30 mins when you don't move it (such as when you watch a movie), and i've been getting the BSOD. I've recently installed a Blu-Ray drive and I think I installed it correctly and all the drivers should be updated...

Thanks

Ian

There are a few errors that may point to hardware issues. One of them related to spdt.sys, which is used for CD emulation. I recommend you uninstall/reinstall any CD emulating software (like Daemon Tools or MagicIso).

Furthermore lets do a disk check. Click Start > Run, type chkdsk /r and press enter. Type Y and press enter to schedule the disk check for the next reboot. Restart your computer and let the disk check run unhindered. Note - this may take some time.

Finally lets do some windows updating, since your service pack (2) is no longer supported by Microsoft.

UPDATE XP

--------------

Your Microsoft Windows installation is out of date. Using unpatched Windows systems on the Internet is a security risk to everyone. When there are insecure computers connected to the Internet, malware spreads faster and more extensively, distributed denial-of-service attacks are easier to launch, and spammers have more platforms from which to send e-mail. Whenever a security problem in its software is found, Microsoft will usually create a patch for it. After the patch is installed, attackers can't use the vulnerability to install malicious software on your computer. Keeping up-to-date with all these security patches will help prevent malware from reinfecting your machine. If you are not sure how to do this, see How to use Microsoft Update.

For additional information, be sure to read "Windows Xp Service Pack 3 (sp3) Information".

Then go here to check for & install updates to Microsoft applications.

Note: The update process uses ActiveX, so you will need to use Internet Explorer for it, and allow the ActiveX control that it wants to install.

Please reboot and repeat the update process until there are no more updates to install.

[ian3]

Hi Elise,

I have done all of the above. Upgraded to SP3 on XP, ran the disk check and uninstalled Daemon Tools. My computer still froze

What do you suggest I do?

Many thanks for your help,

Ian

[Elise]

Please rerun OTL, make sure all options are set to Use Safelist, check All Users and click run scan. Post me the resulting logs.

[ian3]

Here is the OTL logs.

Do you know since when you are getting this problem? If it is since you installed the blue-ray drive, please try to disable it and see if the problem still occurs.

I also see some MS security essentials errors. How long do you have that installed?

[ian3]

I only recently installed MS Essentials as I read somewhere that it could help in the removal of malware - which i thought was the original problem. Should I delete it?

I will try unplugging the blu ray and let you know how it runs.

Thanks

[Elise]

If that doesn't fix the problem. Try uninstalling MSSE. It is a good antivirus program, but I see some errors realted to it, so it is possible it is causing issues.

[Elise]

Hi, are you still there?

[ian3]

Hi Elise,

I'm really sorry for the MIA. I have been pretty busy lately as I have been on call at the hospital. Will try to run it without blu ray and let you know.

Many thanks.

[Elise]

No problem, thank you for letting me know!

[ian3]

No problem, thank you for letting me know!

Hi Elise,

So I unplugged the SATA cable from the Blu Ray drive (i left the power in) and started my computer. About an hour later it froze. So I guess it's probably not a Blu Ray problem?

Thanks!

[Elise]

Based on the Eventviewer errors, it is also possible that Microsoft security essentials is responsible.

Since we have not much to go from here, try to uninstall/disable that.

Does the problem always occur after an hour? Can you verify in the event viewer if an error is noted at the time it crashes?

To access it, click start > run, type eventvwr.msc and press enter.
