First, we need to check your computer and remove whatever was installed that is causing the problem(s).

Click Here to download the current version of HiJackThis.

• Save HJTInstall.exe to your desktop.
• Open Notepad > Click on Format > Uncheck Word wrap, if checked.
• Double-click on the desktop icon for HJTINstall.exe.
• By default it will install to C:\Program Files\Trend Micro\HiJackThis.
• Continue to click Next in the setup dialogue boxes until you get to the Select Additional Tasks dialogue.
  
• Put a check by Create a desktop icon then click Next again.
• Continue to follow the rest of the prompts from there.
• At the final dialogue box click Finish and HijackThis (HJT) will launch.
  
• Close any/all browsers, messenger, mediaplayer, Office and mail client windows and applications.
  
• Click on the 'Scan' button. When the scan is finished, press the 'Save' button. HiJackThis will open a Notepad document with scan in it. Save the log to your Desktop for ease in locating it.
  
• Click on Edit > Select All then click on Edit > Copy to copy the contents of the log to your clipboard.

• DO NOT have HijackThis fix anything yet. Most of what it finds will be harmless or even required.
• Make certain your post shows the entire log, please.
