Greetings Doko and welcome

Please do the following, choosing the instructions appropriate to your version of Windows:

Run a Disk Check on your C: drive in Windows XP:

• Click Start and open My Computer
  
• Right-click on C: and select Properties
  
• Click on the Tools tab
  
• Under Error-checking click the Check Now... button
  
• Mark the box next to Automatically fix file system errors and Scan for and attempt recovery of bad sectors
  
• When the message box pops up, click the Schedule disk check button and restart your computer
  
• Once your computer restarts it will check the drive, don't press any keys so that it is allowed to do so
  

Run a Disk Check on your C: drive in Windows Vista or Windws 7:

• Click the Start button and select Computer
  
• Right-click on C: and select Properties
  
• Click on the Tools tab
  
• Under Error-checking click the Check Now... button and click Continue at the User Account Control prompt
  
• Mark the box next to Automatically fix file system errors and Scan for and attempt recovery of bad sectors
  
• When the message box pops up, click the Schedule disk check button and restart your computer
  
• Once your computer restarts it will check the drive, don't press any keys so that it is allowed to do so
  

Once the disk check is complete and your computer restarts again, please try scanning with Malwarebytes' Anti-Malware once more to see if it now completes.

Please post back with your results.

Thanks

I completed the disk check and once again the scan is stopped on the config.sys file

Can you please copy C:\CONFIG.SYS to C:\CONFIG.TXT and then zip it up and attach it in your next reply.

Thanks.
