Give us these three logs:
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.
Let's use a program to scan for any trojans that may exist. Download
TDS-3. Learn how to use it
here. Make sure to update it after you installed it. You can get the manual updates
here. When you launch the program, it will scan your memory for running processes. This will take less than 30 seconds. Next go to
System Testing on the menu and choose
Full System Scan. After that's finished, post the log file by selecting everything on the top pane (select from bottom to top). If any alarms are found, it will be listed in the bottom window. Please copy and paste that here also if it applies.
