I first had free AVAST which after about two months did not update anymore. I changed to free AVG which did not update anymore after about four months. I finally bought AVG8 for £41 for a two year two computer period which means each computer cost me about $10 per year. It is working beautifully and updates just about every day and sometimes twice a day. I guess when it is free you should at least get your money's worth.
