Double-click on the file you just downloaded.
Click on the "Install" button to install.
It will by default install to the directory - C:\Program Files\Trend Micro\HijackThis
Please do not change the default install location.
Upon install, HijackThis should open for you.

Next click on the "Do a system SCAN and save a log file" button.
HijackThis will scan and then a log will open in notepad.
In the top left of the notepad window click "File" > "Save As" name it hijackthis and then save it to the Desktop.
Please save the log as a text (.txt) file.
In your post, add the log as an Attachment.

* Don't have Hijackthis fix anything yet. Most of what it finds will be HARMLESS or EVEN required.
** Don't use the Analyse This button. It's findings are DANGEROUS if misinterpreted.
