My experience with Avast has been great. I recently made a download of the free version of Avast from the internet. I found it extremely simple and user-friendly. It has proved quite effective in blocking various types of viruses and spyware.
In this context, it’s important to mention that the "smart scan" feature of Avast free antivirus 2015 is extremely quick and helpful.
However, I still feel the free version of Avast antivirus is not ideally designed for online banking and shopping. Therefore, those who love these types of activities should opt for the paid version of the Avast antivirus. So, in brief, my overall experience with the free version of Avast has been great and I highly recommend the product for both occasional as well as frequent internet users. Best of luck!
