Strange you can not do what you need with it. Like Firewall said, Avast works very well with Vista 64. FREE
also. I came close to getting the PC1 Care which is payware. After using it for 30 days I only found it does your defrag for you and cleans up internet clutter. A great program for those that do not really understand keeping your computers house in order....such as my folks. I dumped that and got Avast. It is quite good. Visual and audio warnings if a virus is detected. Visual and audio when you are updated. Contains spyware protection. Small foot print. Some people like AVG which is free but reading up on Avast I found it was a bit better. The only issue I had with Avast was a firewall issue. I would get the warning about my firewall and having windows monitor my firewall, I had to check no and that I would monitor it. No big deal.
