This software is known to be a huge memory hog, it should not be installed on any machine more then 3 years old,or if your PC has less then 2Gb of RAM. Even then you will notice a big slowdown.
It is basically a firewall within your internet program, checking every webpage you visit against a database of nasties, whilst shielding your banking activities against any malware that may be on your system.
Kind of a super Phishing Filter.
Internet explorer 8 and firefox both have phishing filters built in and some security products like Norton or Kaspersky have their own versions which you are prompted to use instead of the standard ones in your browser.
All online banking websites start with HTTPS: which signifies a secure site, this is pretty safe to use, but if you have bugs on your system that can read where you go and record log on data, then you may have a problem.
I personally would not bother with it, update and run your antivirus regularly and also run a program like Malwarebytes ( )to keep everything tip top.
My fear is that if you are offered the software and you decline, will the banks see this as a way to absolve themselves of any blame in the event on online fraud at a later date.
Barclays offer Kaspersky instead of Rapport and I think that this is a better option.
