So today I had a laptop come in with 5 antivirus programs installed on it (yes really five… wtf) so I decided to remove them all but I ran into a problem with uninstalling bigpond security. When I tried to uninstall bigpond security it asks for bigpond username and password. I did not know this information so I had to find out how to do it without the credentials.
Well here’s how it is done.
You need to open the registry editor by typing “regedit” in the start menu search bar and clicking on it.
Once in regedit you need to navigate to:
[HKEY_LOCAL_MACHINE\SOFTWARE\Authentium\Curtains\v1.5]
Once you are there will be two keys starting with LLC, rename these keys
Eg.
[email protected] to [email protected]
LLCID -> oldLLCID
Now close the registry editor and restart your computer.
Now uninstall the program as normal.

Bigpond security seems to be a resource hog. After uninstalling this antivirus software I could see a noticeable improvement.
