I'm new here, just joined today after installing v4. I'm a little old lady from South Wales, UK who loves my computer and manages a network of three machines, two of which are Windows XPHome SP2 and one is Windows Millennium.
I was using the free version for a while as I'm not that impressed with the new version of Ad-Aware, liked it so yesterday bought the Pro version with Lifetime subscription and today, even though I never install beta or pre-release versions of anything on my machine I put v4 on here but haven't done a scan with it yet but do have the real time protection turned on.
So far I'm happy, time will tell
