Please....... please HELP!!!!

 

My name is Alison and I have the technical abilities of a Lima bean :@

 

I had a message come up from Webroot saying something like......on start up a file/program is trying to enter...then there were options....and... I clicked on the one that said   "Block"

Now my laptop will not connect to the Internet at all; it just has a big red cross on the Internet icon.

 

I live in the UK and my laptop in my world. Two years 8mnths ago I became chronically ill, following a routine tooth operation; a viral infection entered and affected my central nervous system, rendering me housebound and mainly bed bound. This isn't a sympathy call....it's just to give you some understanding and put you in the picture of the difficulties I may have with anything complicated so please be patient.  

 

Thank you in advance, Kindly regards Alison :D
