Hello Mark,


Scan with Farbar Recovery Scan Tool

Please download Farbar Recovery Scan Tool and save it to your desktop.

Note: You need to run the version compatibale with your system. If you are not sure which version applies to your system download both of them and try to run them.
Only one of them will run on your system, that will be the right version.

• Double-click to run it. When the tool opens click Yes to disclaimer.
  
• Press Scan button.
  
• It will make a log (FRST.txt) in the same directory the tool is run. Please attach it to your reply.
  
• The first time the tool is run, it makes also another log (Addition.txt). Please attach it to your reply.

Fix with Farbar Recovery Scan Tool

This fix was created for this user for use on that particular machine.
Running it on another one may cause damage and render the system unstable.

Download attached fixlist.txt file and save it to the Desktop:

Both files, FRST and fixlist.txt have to be in the same location or the fix will not work!

• Right-click on icon and select Run as Administrator to start the tool.
  (XP users click run after receipt of Windows Security Warning - Open File).
  
• Press the Fix button just once and wait.
  
• If for some reason the tool needs a restart, please make sure you let the system restart normally. After that let the tool complete its run.
• When finished FRST will generate a log on the Desktop, called Fixlog.txt.
  

Please attach it to your reply.
