Virus help

Hi

 

After getting the backdoor.tidserv!inf infection , I have attemted to follow the instuctions as per the NAV centre. I got stuck on the Recovery console instructions:
  1. Insert the Windows XP CD-ROM into the CD-ROM drive.
  2. Restart the computer from the CD-ROM drive.
  3. Press R to start the Recovery Console when the "Welcome to Setup" screen appears.
  4. Select the installation that you want to access from the Recovery Console.
  5. Enter the administrator password and press Enter.
  6. Type CD System32
  7. Press Enter
  8. Type Expand %DriveLetter%\i386\advapi32.dl_
  9. Press Enter
  10. Type exit
  11. Press Enter. The computer will now restart automatically

Step 8 is the confusing one for me as I do not know EXACTLY what to type????? Subsequently my machine "seems" to be running fine and NAV is not picking up anything but when I tried to run a defrag and chck for disk errors, I received a message saying that the NTFS boot sector is unreadable! I am thinking that this is a  result of not completing the Recovery console step when removing the virus.

 

Please can someone help me as I have battled for 12 hours now. A month ago fossy710 had a similar problem but I do not know if that solution will be the same for me

 

Look forward to your expert advice
