Computer Infected Whole Family Of Viruses

I am servicing computers everyday for both business and home users and the vast amount of computers are infected with this whole family of viruses by names like Personal Security, Window Anti-virus, Antivirus7, Security Guard etc.I see these ransom-ware infections getting past everything from the free Anti-virus programs to the most expensive anti-virus programs, especially with home computers that are use for Entertainment Purposes and always because the users were browsing the Internet and are tricked into clicking on a fake warning of infection or security risk. Once they are tricked into that initial click, life goes downhill rapidly as the infection installs itself and then takes deeper root as the user clicks on subsequent fake screens. If they don't register the fake program, it will proceed to convince them to register by progressively turning off more and more Windows features.My question to the knowledgeable users of this forum is:Does anyone know of an antivirus/spyware program or combination of programs that can catch these infections as they initially try to install from that first ill-fated click while browsing the Internet?I have tried all the Big names to varying degrees of disappointing success.Would registered versions of MalWarebytes or Super AntiSpyware be effective?
