Neither. AVG sucks if you look at AV comparatives. Don't get me started on McAfee. Not free, not effective, useless.

Use Avira or avast. Personal recommendation avast v6. Play nice with lots of my security combo. Free, effective, light. Don't know why people say pay antivirus better. Was a user of Kaspersky until I found avast v5 for free. Never look back. You can set up your own security combo for free. Free security combo = free internet security.

Forget to mention, Iobit was caught using Malwarebytes database. So I will never trust another program from Iobit.
