You're doing fine. This should solve the redirection problem:
Use hijackthis to fix these two entries:
R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Start Page = http://softwarereferral.com/jump.php...MjI6Ojg5&lid=2
O24 - Desktop Component 0: Privacy Protection - file:///C:\WINDOWS\privacy_danger\index.htm
Delete this file:
C:\WINDOWS\privacy_danger\index.htm
To make things a bit easier, instead of using explorer [it is only a UI] use Task Manager instead.... even without your explorer running you can start it with Ctrl-Alt-Del. Then go Files > New Task[Run] and paste in:
H:\Help\HiJackThis.exe
To delete that file, run instead:
cmd
..and paste into the cmd window:
del /f C:\WINDOWS\privacy_danger\index.htm
Now try with a freshly dl'd copy of MBAM [or Run from the dl site]. Only if that will not work then do this:
==Download this file to your DESKTOP: http://download.bleepingcomputer.com/sUBs/ComboFix.exe
-Important! : disconnect from the web, turn off your Antivirus, Antispyware and Firewall for the duration of this scan. Don't forget to reset them before you go back on the web!
- to run it dclick the Combofix.exe icon and follow the prompts to start it. When finished, it will produce a log, C:\Combofix.txt - post that log in your next reply.
A word of caution - do not touch your mouse/keyboard until the scan has completed. The scan will temporarily disable your desktop, and if interrupted may leave your desktop disabled. If this occurs reboot to restore the desktop.
