Need computer help

I need assistance with my computer. It will not let me download software. It used to allow me but not. I have run all the virsus stuff and that cleaned out a whole LOT of junk on my computer but I can't seem to get it to allow me to download... even the microsoft expert fixes will install but not download. Does anyone have any suggestions for me? Or does anyone know someone or somewhere I can take my computer to get it fixed? Thanks Ladies, you've always been so helpful!

My husband is an engineer that fixes computers as a side-line. I also have a IT guy that may fix computers on the side. If you are interested send me a private e-mail and I will send you their info.
