I have myself not heard of 'Trusteer Rapport' but was just looking and reading about it:
Online Banking Security | Trusteer
So I cannot give an opinion but I am sure others can.
I did however check which banks are recommending it and mine is.
Here are some questions asked to my bank about there software:
Do I still need anti-virus software?
Absolutely. Anti-virus software is a vital part of your computer’s defences, and you need to make sure it’s up-to-date. Rapport is designed to work alongside your anti-virus software and firewall - it’s not designed to replace them.
How am I protected?
Firewalls, anti-virus software and Rapport work in very different ways:
Rapport strengthens your online security by ‘locking down’ the connection between your computer, keyboard and Alliance & Leicester internet banking. It helps stop your data going to counterfeit sites, so you can be safe in the knowledge that only you are transacting on your account.
Anti-virus software helps to stop threats, by scanning your PC and looking for suspicious files, whereas firewalls hide your computer from attackers, and helps stop criminals getting data in and out of your computer.
Rapport doesn’t replace the benefits of anti-virus and firewall software or your unique image and phrase when accessing our internet banking – it works alongside them to provide increased protection when transacting online.
To defend your personal details, you need to use Rapport alongside anti-virus software and a firewall.
Do I need to download Rapport onto every computer I use?
Yes – in order to be fully protected when banking with us online, you should download Rapport onto each machine you use – just like anti-virus software.
If you wish to download Rapport to a work PC, check with your employer as they may not allow downloads to their PCs.
How do I know I’m protected?
You need to look out for the Rapport icon which appears next to your browser’s address bar.
You’re protected – the icon is green when your information is safe:.
It can also be setup to protect data on other websites not just your bank.
Kaspersky 2010 is good and as for high street purchase I would just say look to who is selling it at the best lower price.
Buying online may mean you get a download.Buying from a store you would receive the install disk and key code to activate it.
I see no conflict in running both the above named progams.
I hope this helps?
I am sure others will input with more information for you.
PS: Get rid of Norton as soon as you can.If she has problems removing/uninstalling Norton then you can use the uninstall tool:
