I m using avast6 free version in my netbook from the day i brought it. i am happy with version6 as it is very light on processing. I am concern about how much processing juice a7 wil intake as my netbook have no high end hardware support to offer. What i have in short is, 2gb of ram & 1ghz amd dual core cpu. So wil avast7 going to be process heavy? Should i go with the new one or stick with the one i am satisfied with til now???
