How can I get my Background settings back?

[pivoxa15]

I have a version of the Windows XP.

I use to be able to change my background on my desktop by right click, properties, background.

But now, when I go into properties, the option of changing my background is gone. I now only have two choices Screen Saver and Display (colour resolution, screen size etc).

Now when I right click a picture in My Pictures and set it as my background, it does not work.

The background I have now says something like Warning Your computer might be affect with adware or spyware and it tells me to install their latest version of their Software to protect my privacy by clicking a link that leads me to their webpage. I want to get rid of this background and put my own on (nor do I want their software).

I have uninstalled this program but the background is still there.

Anybody know how I can get my background settings back so I will be able to change my background?

Thanks

Windows Registry Editor Version 5.00

save as a .reg file and import it

 iammichael5,

Are you suggesting me to go to the link

Hkey_current_user\software\microsoft\windows\currentversion\policies\system

If so than as you can see it does not lead me to a specific website?

What is
nodispbackgroundpage=dword:00000000


Can you please clarify which file I need to save and what does import mean?

Thanks

Copy the red text into notepad and save it with a .reg file extension. Then double-click on it to - merge - it (add the key) into your registry.

Mac, I did what you told me to do

copied the red text into notepad and saved it with a .reg file and double clicked on it. Some message came up and I clicked ok to them.

So the file was merged into the registry but nothing happened. I still could not change my background and the 'background' option that should normally be in 'properties' was still not there - even after I restarted my computer.

What should I do?

Thanks

The background I have now says something like...

"Warning Your computer might be affect with adware or spyware."

 ...and it tells me to install the latest version of their Software to protect my privacy by clicking a link that leads me to their webpage.

This is one of the many pests going around.

You should ignore these messages at all times.

Scan with AdAware SE, SpyBot SD and when the system is clean, install SpywareBlaster.

If you need a good anti-virus then AVG Free Home Edition is excellent.

All of these are freeware programs.
