I was searching through my startup processes in msconfig when I came across a process called Unattend0000000001{2F0CCE2D-26B0-45A0-90A2-BEE09B5FC562}, located in C:\Windows\test.bat. I looked this up on Google to try to find out what it is but couldn't get anything concrete. Still, I am worried this might be a rootkit. Could anybody please help?
Thanks,
James

We can try a scan and see what shows...

The process of cleaning your computer may require temporarily disabliling some security programs. If you are using SpyBot Search and Destroy, please refer to Note 2 at the bottom of this page.

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • 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.
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.

Note 2:
-- MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes (like Spybot's Teatimer), they may interfere with the fix or alert you after scanning with MBAM. Please disable such programs until disinfection is complete or permit them to allow the changes. To disable these programs, please view this topic: How To Temporarily Disable Your Anti-virus, Firewall And Anti-malware Programs

Thanks for the reply, rigel. :thumbsup:
I've run MBAM scans before and came up with nothing, but ran one anyway just to be safe. I can't for the life of me find the attachment button today so I'll just paste it here.

Still, nothing. :\ I've noticed that my computer is taking a longer time than usual shutting down, though, and the resources on my computer are being taken up for no reason (to the point that it was preventing my wireless from working), which I think are classic symptoms of rootkits (but I could be wrong).
Thanks again for your time.

A rootkit scan is the next step :thumbsup:

Install RootRepeal

Click here - Official Rootrepeal Site, and download RootRepeal.zip. I recommend downloading to your desktop.
Fatdcuk at Malwarebytes posted a comprehensive tutorial - Self Help guide can be found here if needed.: Malwarebytes Removal and Self Help Guides.
Click RootRepeal.exe to open the scanner.
Click the Report tab, now click on Scan. A Window will open asking what to include in the scan.
Check the following items:
Drivers
Files
Processes
SSDT
Stealth Objects
Hidden Services

Click OK
Scan your C Drive (Or your current system drive) and click OK. The scan will begin. This my take a moment, so please be patient. When the scan completes, click Save Report.
Name the log RootRepeal.txt and save it to your Documents folder - (Default folder).
Paste the log into your next reply.

RootRepeal only supports x86 OSs, and I have an x64 OS. :thumbsup:

You are correct... we need to use Sophos. It does support the 64 OS

Please download Sophos Anti-rootkit & save it to your desktop.
alternate download link
Note: If using the vendor's download site you will be asked to register with MySophos so an email containing an activation link can be sent to your email address.

Be sure to print out and read the Sophos Anti-Rookit User Manual and Release Notes.
  • Double-click sar_15_sfx.exe to begin the installation, read the license agreement and click Accept.
  • Allow the default location of C:\Program Files\Sophos\Sophos Anti-Rootkit and click Install.
  • A message will appear "Sophos Anti-Rootkit was successfully installed. Click 'yes' to start it now". Click Yes.
  • Make sure the following are checked:
    • Running processes
    • Windows Registry
    • Local Hard Drives
  • Click Start scan.
  • Sophos Anti-Rootkit will scan the selected areas and display any suspicious files in the upper panel.
  • When the scan is complete, a pop-up screen will appear with "Rootkit Scan Results". Click OK to continue.
  • Click on the suspicious file to display more information about it in the lower panel which also includes whether the item is recommended for removal.
    • Files tagged as Removable: No are not marked for removal and cannot be removed.
    • Files tagged as Removable: Yes (clean up recommended) are marked for removal by default.
    • Files tagged as Removable: Yes (but clean up not recommended) are not marked for removal because Sophos did not recognize them. These files will require further investigation.
  • Select only items recommended for removal, then click "Clean up checked items". You will be asked to confirm, click Yes.
  • A pop up window will appear advising the cleanup will finish when you restart your computer. Click Restart Now.
  • After reboot, a dialog box displays the files you selected for removal and the action taken.
  • Click Empty list and then click Continue to re-scan your computer a second time to ensure everything was cleaned.
  • When done, go to Start > Run and type or copy/paste: %temp%\sarscan.log
  • This should open the log from the rootkit scan. Please post this log in your next reply. If you have a problem, you can find sarscan.log in C:\Documents and Settings\\Local Settings\Temp\.
Before performing an ARK scan it is recommended to do the following to ensure more accurate results and avoid common issues that may cause false detections.
  • Disconnect from the Internet or physically unplug you Internet cable connection.
  • Clean out your temporary files.
  • Close all open programs, scheduling/updating tasks and background processes that might activate during the scan including the screensaver.
  • Temporarily disable your anti-virus and real-time anti-spyware protection.
  • After starting the scan, do not use the computer until the scan has completed.
  • When finished, re-enable your anti-virus/anti-malware (or reboot) and then you can reconnect to the Internet.
