I installed on my Windows 7 ultimate and everything went fine until I ran a full system scan .......after two days this antivirus kept being stuck at 80% of the scan and the worst was it was using 99% of the pc's ram memory, I had to cancel the task. I went and bought Avira Pro and this one is working perfectly without any issues.

Desperately needed some printed guidance to study to make this software behave the way I wanted it to. This book is just the ticket. And it arrived in excellent condition.

A great guide. Used in conjunction with the Brandt guide. Really helpful to have both for our car trips around Iceland.
