Thank you Eddy - I did not mean to infer that Avast has something to do with the windows security downloads - only since this is a new program on my pc, I wasn't sure if all of Cleanup tweaking and optimizing may have changed something which interfered with the downloads. As I said, I did figure it out and now the downloads seem to download correctly. Also, I do not have any immediate plans to ask for a refund. Just wanted to know where to go to get one if I do need one. Again, do appreciate your time and patience with this matter. Thank you.
