Post a hijackthis log for me.

Most of what HijackThis lists will be harmless or even essential, don't fix anything yet.
Post the logfile that HijackThis produces
highlight and copy everything in that log and then click on copy, then come to the forum in your reply and click on paste and it will copy it there.
Its really simple. When you ran hijackthis did it popup with a notepad log? If so then all you need to do is click on the edit menu, click on select all, click on the edit menu again, click on copy. Then come to forum and start your reply and right click the mouse and click on paste.
I can't tell if your system is totally clean unless I see the hijackthis log.
Then press and hold the shift key while right clicking on hijackthis to get the run as admin option to appear and click on it.
What about just right clicking on the hijackthis icon?
What operating system are you running?
OK. Please open hijackthis and click on "do a system scan and save a logfile". If for some reason you get a error message about not being able to access the hosts file, then you will need to run hijackthis as admin. To do this, on some systems all you need to do is right click on the hijackthis icon on your desktop and click on "run as". If the "run as" option doesn't appear in the right click menu, then press and hold the shift while right clicking on the hijackthis icon on your desktop and then the "run as" option should appear in the right click menu.
It's the same thing, just click on run as.
