for a few days i've noticed that when i turn on my pc a google chrome window opens and is directed to sd-steam.info. i know that it makes a file in the registry to do this and should i remove it, a command prompt window opens for a split second and adds it back. after this happening a couple of times i decided to leave it alone for now. from what i gather this is a somewhat common adware so any help would be very appreciated.

Welcome to BC...

 

Use CCleaner to remove Temporary files, program caches, cookies, logs, etc. Use the Default settings. No need to use the

Registry Cleaning Tool...risky. Pay close attention while installing and UNcheck offers of toolbars....especially Google.

After install, open CCleaner and run by clicking on the Run Cleaner button in the bottom right corner.

CCleaner - PC Optimization and Cleaning - Free Download

 

Download Malwarebytes' Anti-Malware from Here

Double-click mbam-setup-2.X.X.XXXX.exe to install the application (X's are the current version number).

  • Make sure a checkmark is placed next to Launch Malwarebytes' Anti-Malware, then click Finish.
  • Once MBAM opens, when it says Your databases are out of date, click the Fix Now button.
  • Click the Settings tab at the top, and then in the left column, select Detections and Protections, and if not already checked place a checkmark in the selection box for Scan for rootkits.
  • Click the Scan tab at the top of the program window, select Threat Scan and click the Scan Now button.
  • If you receive a message that updates are available, click the Update Now button (the update will be downloaded, installed, and the scan will start).
  • When MBAM is finished scanning it will display a screen that displays any malware that it has detected.
  • Click the Remove Selected button.
  • MBAM will now delete all of the files and registry keys and add them to the programs quarantine. When removing the files, MBAM may require a reboot in order to remove some of them. If it displays a message stating that it needs to reboot, please allow it to do so.
  • While still on the Scan tab, click the link for View detailed log, and in the window that opens click the Export button, select Text file (*.txt), and save the log to your Desktop.
  • The log is automatically saved by MBAM and can also be viewed by clicking the History tab and then selecting Application Logs.

POST THE LOG FOR  REVIEW.

 

Download AdwCleaner by Xplode onto your desktop.

  • Close all open programs and internet browsers.
  • Double click on adwcleaner.exe to run the tool.
  • Click on Scan button.
  • When the scan has finished click on Clean button.
  • Your computer will be rebooted automatically. A text file will open after the restart.
  • Please post the contents of that logfile with your next reply.
  • You can find the logfile at C:\AdwCleaner[S1].txt as well.
  • download Junkware Removal Tool to your desktop.
  • Shut down your protection software now to avoid potential conflicts.
  • Run the tool by double-clicking it. If you are using Windows Vista, 7, or 8; instead of double-clicking, right-mouse click JRT.exe and select "Run as Administrator".
  • The tool will open and start scanning your system.
  • Please be patient as this can take a while to complete depending on your system's specifications.
  • On completion, a log (JRT.txt) is saved to your desktop and will automatically open.
  • Post the contents of JRT.txt into your next message

That was easy enough....you're welcome..

I suggest you scan using the other programs, too. Especially AdwCleaner and Junkware Removal Tool.

yeah i decided to use adwcleaner as well just to be sure and for completeness' sake and it turned out clean. after a couple of restarts and the file not being added to the registry after about 2 hours (the command prompt usually ran immediately after deleting the registry file) i can safely say it's been dealt with.
