I am the person that will be helping you today.
Are you referring to your Webroot Account? I see that you typed "Webfoot". I am assuming that is a typo.
You can download Webroot from the following page and install it: http://www.webroot.com/download
After installing the application, you can enter the serial code you already have. If you have any problems with that, I can remote in and do this for you, if you wish.
I look forward to hearing your feedback concerning whether or not your problem is fixed.
I hope to hear back that all is working. If this is so, please do not forget to rate my help on the top of this page (choose the number of stars and click the Submit button). If it is not, please respond below.
I will be standing by,Jason
May I ask if you need any additional help or did that work for you?
