I like that it is very easy to use - even when you are not familiar with computers or security systems in general! It has never failed me once since purchasing over 2 years ago now; however if there was one thing i would change about this product its price point compared other similar products out there at lower prices than what pclogins charges per year as their subscription fee!! This protects my computer from virus threats by scanning files before they open/run them so no damage occurs because of malicious code being run inside windows itself without user interaction etc..
