I have been using Mcafee for past few years , but after rigorous Google research found this one worth trying. What I found is that none other than Kaspersky is offering extra product features apart from a normal anti virus within this product range.Kaspersky's intelligence and their technology which they offer at reasonable price is something inimitable.Take for instance their Sand Box technology which can be used to run programs or files that are potentially detrimental to your computer or their Instant Messenger protection or two way firewall system which shields your system from external attack.
