Norton internet 2012

I downloaded from the website on to my new Lenovo laptop and from the point I down loaded it I have had an error msg. I have had 8 different tech guys remotely trying to fix it everyday from Friday for at least 6 hours a day they keep deleting things out of my registry (which I hope will not mess up my brand new pc). My pc has been left in safe mode AGAIN they just do the same things over and over again. I AM SO FED UP NOW I would like someone to fix this ASAP so I can enjoy my new laptop instead of spending hours online or on the phone!!
