Hi,
Download CleanUp! and install it, do not run it now.
Download CWShredder . Download SpSeHjfix to the Desktop and then right click a blank part of Desktop & select new folder, call it spfix unzip the file into that folder.
Disconnect from the net and Close ALL OPEN PROGRAMS.
Run SpSeHjfix112 and click on "Start Disinfection". When it's finished it will reboot your machine to finish the cleaning process. The tool creates a log of the fix which will appear in the folder.
If it doesn't find any of the SE files or any hidden reinstallers it will say system clean and not go on to next stage.
Now run the CWShredder, and click "Fix" button.
Now, run CleanUp!, click the "Options" button. Here move the "Quick Setup" slider to "Thorough CleanUp!" and click "OK" to warning message. Exit from Options and in the main window, click "CleanUp!" to start cleaning. After cleaning, click "Close" and choose "Yes" to restart the PC.
Run HijackThis, click the "Do a system scan and save log" button, and post the log here along with SpSeHjFix log.
