WHAT IS THIS ANNOYING THING?

[glad rag]

hxxp://cxpfy...com keeps on opening a small window asking for authentication....

Anyone help please...

Something to do with godaddy.com. Whatever that is.

OK how do you kill it?

I think you've been hijacked by one of the Babylon toolbar exploits

Usual answer: one by one in sequence
delete all temp and temp internet files
run TDSSKiller
run RKill
run Hitman Pro
run Smitfraudfix (if 32-bit OS only)
run Combofix
scan with Malwarebytes
scan with Spybot S&D
see what happens
You may need to reset the Windows or IE shells - post back if you still have a problem

What antivirus / security software do you have on the machine?
Whatever it is, it didn't work

You may need to reset the Windows or IE shells - post back if you still have a problem ?? So what's this??

Still there after the all above apart from Spybot S& D, I was warned off this as it may corrupt the windows update register thus leading to the "this is not a licensed version" yabba on bottom rh corner of screen....

Try combofix from, say, here (http://www.infospyware.com/antimalware/combofix/). DL to your desktop.

Disable your antivirus, run Combofix, let it update if it wants to, follow the prompts. Re-enable your antivirus.

whoever told you that was speaking out of his rear orifice Windows vista help actually, but YES, you're probably correct.

But despite using both S & D and Combofix [boy does THAT go to town] the b@stard is still there.

OK I'm thinking deleting FF, then clean install. Any other ideas?
