Ha Ha, I actually came back to let you know that my bout of dementia relapsed slightly (see even the spelling of dementia is now correct) and I spotted what I was looking for on the net.
*********************************
The problem is cause by what is known as 'Intellitxt', there are several ways to stop it.
A. Install Add-Block, I think you will find Add-Block is already setup to block intellitxt.
B. Run a Malware program on a daily basis.
C.
Add an entry in the HOSTS file.
Make sure that Windows is showing hidden files and is not hiding file extensions for known file types (access these settings from Control Panel> Folder Options> View)
Then find the HOSTS file at:
[C:\Windows\System32\Drivers\etc]
Open the HOSTS file with notepad. Add these lines, each on a separate line, just below "127.0.0.1 localhost" and "::1 localhost"
127.0.0.1 us.intellitxt.com
127.0.0.1 vibrantmedia.com
Click on File> Save and close the HOSTS file.
More on the HOSTS file at
http://mvps.org/winhelp2002/hosts.htm and
http://www.accs-net.com/hosts/This (frequently updated) HOSTS file will block many ads *and* sites hosting malicious software.
It can occasionally block a site you want to access- read the article so that you know how to temporarily disable it.
http://mvps.org/winhelp2002/hosts.htmAnother option is:
Internet Options> Security> Restricted Sites> Sites, place these URLs in Restricted Sites:
*.us.intellitxt.com
*.vibrantmedia.com
Hope this helps,

(OK, I altered it, but only slightly)
