I have had Kapersy Internet Security for the past three years and I LOVE it. When I bought my computer three years ago I asked the computer tech about anit virus and internet securtiy, I figured he was going to suggest one of the leading national brands that we hear so much about. I was surprised when he recommended Kapersky. I had never even heard of it before but the guy was so sure about it that I said I would give it a try. Well, three years later and 2 renewals later I am not dissapointed at all. The computer tech explained how Kaperskyy takes up less memory on your computer and I can't for sure say that is true compared to other products but I know it doesn't seem to take up much space compared to other programs. I have never had a computer crash issue and when I have never had a virus issue with my computer either. It seems to do a good job and catching and putting into quarantine viruses, malware, adware, etc. I am not a comptuer genius by any means but I am happy with the protection I am getting from Kapersky.
