Tills a lot of sites that rely on money transactions and transfers use Trusteer and when they note that you do too, you will always have a smoother transaction and in some case no bank verification fannying about to go through. Like you I first let it upload when I started online banking because the bank recommended it was installed. Now if you do not follow the advice of your bank and stop it operating, and at some stage have a hack or security breach, is the bank going to say ……...your fault, you didn't run Trusteer? I am happy with it and have said so on previous threads in the past. There is always someone that is liable to poo poo it on here though with recommendations for other 3rd party bolt on measures. Trusteer is non intrusive and you will not be spammed out with emails to upgrade, or warnings that you are about to die if you do not purchase the latest all singing all dancing version.
