I hate to say it but they made the Free Version too Good for their own Good. In this Economy people DO FREE. That Free Avira has been the best AntiVirus "Ever" bought or paid that I can think of. I love how light it is on a System and is very user friendly. I tried the bought Version for a short while and favored the Free.

They have it for a 30 day trial and it only costs $30 such a great price for such good Stuff. If you have never tried the bought version I suggest you do. It is Fantastic.
