Anti-Virus Software

Here’s something we all have in common.The virus.What programs do others use,and why?
I use to use Norton,untill it was taken over by Symantic,got hacked so many times on the web,that it was’nt worth installing,plus,trying to uninstall the damn thing took forever,and usually wrecked my original configeration.McAfee,Anti Vir,AVG,the list is endless.Any thoughts.
