Before you do anything else, please create a folder for HijackThis and put it in a permanent folder (like C:\HJT) instead of the Desktop. This is required because HijackThis will create backups and we don't want them to be deleted.
Please print out or copy this page to Notepad. Make sure to work through the fixes in the exact order it is mentioned below. If there's anything that you don't understand, ask your question(s) before proceeding with the fixes. You should
not have any open browsers when you are following the procedures below.
I really do not see much that could be causing your system to be overly slow. Lets try this to see if there is something trying to hide from HJT. 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.
Run HiJack This and post us another LOG file after the completion of the TDS scan.
