It is one of the internet security that is used as total security.The validity is around one year and I had nice experience with this kaspersky antivirus.
This one protect our computer from malware attacks, viruses, spyware etc.The price is little high as compare to other brands but quality in very nice. without any doubt it provides complete protection.It does not consume resources and makes your computer smooth and virus free.
It helps to limit access to insecure and malicious sites and it protects data.You have to keep updating your kasperky database so that it will have all the information about the new virus also.
It doesn’t make your system slow but when you use licence version then in the last 15 days your system will become slow.
