Can we please get back to the reason for this thread? I would endorse what Saraceno says. Have been running KIS since version 6 through to the latest 2009 with little or no issues. I am also a Gold Beta Tester...so I am nailing my colours to the mast here. But I would say that if you want a good perspective of the product then you should log onto the Kaspersky Lab Forum: (http://forum.kaspersky.com/index.php?showforum=4) and check out what is being said there as it reflects the position of current users (not disrespect to Wilders but the KL Forum is dedicated and therefore likely to be somewhat more represntative, etc., IMHO) I would close on a personal note by saying that my base line loyalty is to quality and I will go with what I consider best or one of the best. I was a NIS user for many years until NIS2006 became unusable, IMHO...and therefore I switched. I note that NIS2009 is getting excellent reviews, IMHO on a par with KIS, but am content to stay with KIS. Hope that this help?
