Download the free HijackThis utility. Once downloaded, follow these instructions to install and run the program:
Create a folder for HJT outside of any Temp/Temporary folders and move the HijackThis.exe file to that folder now. A folder such such as C:\HijackThis or C:\Spyware Tools\HijackThis will do.
Run HijackThis, but do not have HJT fix anything yet; only have it scan your system! Once the scan is complete, the "Scan" button will turn into an option to "Save log...".
Save the log in the folder you created for HijackThis; the saved file will be named "hijackthis.log". The log file will open in Windows Notepad once you save it; cut-n-paste the entire contents of the file from Notepad and post it here.
