Will my security software interfere with the service?
Possibly. Norton Internet Security (NIS) and Norton Anti-Virus/Firewall may prevent the service from working. To navigate this problem you must temporarily disable the “Security” option in these products in order to access Maths-Whizz. To do this, select the NIS Security Center option within your Norton software and turn the first option under “Security” to “Off”. Then refresh your browser before trying once again to access the service.
If you have a different firewall installed (software that protects your computer from viruses, etc.) this may be responsible for the problem. Try temporarily disabling it to test whether this assists Maths-Whizz.
