Right click on
http://www.silentrunners.org/Silent%20Runners.vbs and choose Save As...Save it to your Desktop. Make sure you have disabled any programs that may block/disable scripts (ex: Ad-Watch, TeaTimer, Norton, etc.). Double click on 'Silent Runners' to run it. This will take a few minutes. It will create a file called 'Startup Programs' followed by your computer name and current date. Open up that file and post all the contents here in your next post.
Download DllCompare
http://www.greyknight17.com/spy/DllCompare.exe and run it. Click on the 'Locate.com' button. Wait a few seconds and then click on the 'Compare' button. Let it run, then click on 'Make a log of what was found'. Post that log here. Note: If you are having problems using DllCompare (16 bit error), copy autoexec.nt from the C:\WINDOWS\repair folder to C:\WINDOWS\system32 folder. Now try running DllCompare.
