Don't buy macafee. I own macafee antivirus multi device yesterday some virus infected by laptop and macafee didn't even detected it.A full system scan detected it but macafee was unable to remove it. Now I purchased eset system security 10,it detected it and removed the virus successfully. I had been using eset 9 earlier and must say eset is better does the job of antivirus unlike macafee which has got only fan following no use
