about a week ago i installed some bad files and a lot of my account settings and network options were changed. i tried to change them back and they would not. Also, some files became read only files and i when i try to change that, it doesnt work. what would you suggest should i do to find out what causing this and remove it?

Please download and install the latest version of HijackThis v2.0.2:

Download the HijackThis Installer from this link: HijackThis

1. Save " HJTInstall.exe" to your desktop.
2. Double click on HJTInstall.exe to run the program.
3. By default it will install to C:\Program Files\Trend Micro\HijackThis.
4. Accept the license agreement by clicking the "I Accept" button.
5.Click on the "Do a system scan and save a log file" button. It will scan and then ask you to save the log.
6. Click "Save log" to save the log file and then the log will open in Notepad.
7. Click on "Edit > Select All" then click on "Edit > Copy" to copy the entire contents of the log.
8. Paste the log in your next reply.
9. Do NOT have HijackThis fix anything yet! Most of what it finds will be harmless or even required.
