Browser won't remain as default

Hi,
Did you Uninstall another browser ?
I would imagine you might be referring to default search and not default browser,
Open ie and use Alt+TA or Gear symbol and Manage add-ons,
Go to the Search providers section on the left column and see what's listed,
Also go to the Toolbars and extensions section,
On the bottom left change the view option to Show All add-ons,
Post a screen shot of both sections if you want to but the Toolbars... is what I'm most interested in,

You can if you want too
But I suspect you have a browser hijacker so it would do little good at this point,
As you said now a couple times the setting does not stick and you have no other browsers installed,
We can just skip to the scanners bit if you don't want to take screen shots of the sections I wanted,
Post the scan results,

ThrashZone,

Meant to include in last reply that I'd checked IE 'Add-Ons', nothing not expected. I disabled all and issue still there.

Thanks for link to cleaner which I've downloaded and run twice. '...R0.txt' is results of first run and clean. '...R1.txt' is second run; this one, as expected, reports clean system.

Even after running the cleaner, opening IE still asks if you want to make IE the default browser. Any further suggestions that I could look at/try ?

Edit: Perhaps reason why IE won't remain as default is that it can't be set in first place...........I've noticed that the "Apply" button is greyed out i.e. disabled. Assume in this instance nothing can be set. How do I get the "Apply" button functioning?
Edit2: Apply button greyed out by default until you want to do something so this not the problem. "Apply" button functioning correctly.

Can someone tell me how I can reinstall a fresh copy of IE?? I've got a currently unresolved problem with IE remaining as the default browser which I feel might be resolved by performing a complete fresh install of IE

I'm currently running IE11 with Windows 7 64bit. I've been to Microsoft's Download Centre and downloaded a new copy of IE11 (IE11-Windows6.1-x64-en-us.exe) but when I come to install I get the window "Internet Explorer didn't finish installing" stating "Setup can't continue as a more recent version is installed on your computer" (???).

I've uninstalled IE11 and reverted to IE10 but my initial problem (default browser) remains and I get same result when trying to perform a fresh install IE10

I've gone back to IE9 but same results. I've now updated back to IE11 via windows update site.

Does anyone know why I can't perform a complete fresh install (of any version) of IE, whether I can, and how ?

Edit: I was trying to re-install IE over itself i.e. re-install IE11 when IE currently installed. Not sure why I get the message as I would of assumed the download centre would have the latest. No problem uninstalling, say IE11, and reinstalling when IE10 current version.

Hi I'm not sure why your running the scanner from H-Drive
The instructions specify to download the file to your Desktop and run as administrator/ Please repeat,

It did find Delta references,

With Delta I'm not sure what you call expected post the add-ons page.

Also post which security suite you have installed,
Cheers.

This is actually the removal guide,

As far as re-installing Internet explorer goes,
See a tutorial here to Reset Internet explorer,
Pay close attention to #7 if it doesn't show all green checkmarks the reset will fail because of the Malware you've downloaded most likely included in some other software from CNet........ ?

After Resetting ie9 or 10 notice the last process after resetting and re-opening Internet explorer for the first time,
I would add this to the tutorials process
