Some questions please....
1. What is your operating system and service pack and is it up to date with both critical and non-critical updates?
2. What is your default browser and what version of Internet Explorer is installed (open > Help > About)?
3. What version of McAfee protection is this...what does it say on the box?
By the way true support is available free by Chat through McAfee Support > Home & Home Office link at top of this page 24/7.
Once activated you will probably qualify for 30 days free telephone technical support too.
