Just a question about the state of antivirus technology

[Barbara Griffith <Barbara.Griffith () COLORADO EDU>]

I'm confused about the heuristic setting in various antivirus products. We used to set it high, and never had any 
complaints. But now I'm hearing from some experts that heuristic technology is no longer considered to be very 
effective, and may cause a performance hit. I went online and got even more confused. Many sites still mention and even 
recommend it. 

Any advice for the perplexed would be welcome.
