Your computer will now download the file to your computer and save it on your Desktop. When it is done downloading you will now find an icon on your desktop that looks like Figure 3 below.
Disable any script-blocking programs and then double-click on the DDS.scr icon to start the program. If you did not disable a script-blocker that may be part of your antimalware program, you may receive a warning from your antimalware product asking if you would like DDS.scr to run. Please allow it to do so.
Once you double-click the icon a Windows security warning may also appear asking if you are sure you would like to run the program. This warning is shown in Figure 4 below.
Click on the Run button to start DDS. If no warning appeared, as shown above, then you should just continue reading.
DDS will now display a small black window providing information as to what DDS is doing on your computer as shown in Figure 5 below.
DDS will now start scanning your computer and compiling a variety of information about what programs are starting on your computer, what files have been recently created, and the general configuration of your computer. When DDS has finished scanning, all of this information will be compiled and be displayed in two Notepad windows named dds.txt and attach.txt as shown below.
You will then be shown a small box giving instructions as to what you should do with these files. Feel free to close this message box by pressing the OK button.
We now need to save the two log files that were created. First click on the DDS.txt window and click on the File menu and then select Save As... menu option. You will now be presented with a screen similar to Figure 8 below asking where you would like to save the file.
Click once on the Desktop button, designated by the red arrow in the figure above, to save the file to your Desktop and then press the Save button. The DDS.txt log will now be saved to your Desktop. Now click on the Attach.txt Notepad window and perform the same steps to save that file to your Desktop as well.
Please copy and paste the contents of the dds.txt log and the attach.txt log in your next reply.
