AVG Free is an excellent program, however over the years it has become very bloated, so if you are using an older computer (2-3 years) I would go for one of the others.
NOTE: Remember AVG free is not a full security suite and so is limited to mainly virus and Malware detection.
If you shop around online you will find full security suites are relatively cheap these days, so is another option to consider.
WARNING: Avoid MacAfee like the plague as it is pretty much useless in all departments.
Hope this helps
Bill
