Larry and Salaci, thank you much for your help. I am on line with Linux ubuntu. The feeling is wonderful, although I am not sure what to do next, maybe try to install my email and look for news posts. Or should I now refine my operating system? If you pass by, give me a hint what next to do. Again, this is wonderful and I am so thankful for your help. taco

difficult to know what to suggest...you should try to do something that you want to do (hey, maybe an office task, like using a wordprocessor or a spreadsheet) rather than something I would like to do.

At some point you will have to install a package and, just so that you know how easy it can be, go into your package manager (synaptic, probably, but other GUI tools to do similar things exist), select a package and let the system install it. For the purposes of checking it out, it could be anything, but you might as well select something that you might want.

Once you see how well this works, the system of scouring around the net, finding a software package that may or may not have malware attached, and messing around with .dlls will seem awfully primitive, so it seems like a worthwhile thing to feel confident about doing.

salasi is right, get familiar with your operating system and the terminology first then see what you might want to do. One suggestion is to read the Ubuntu forums here and use terminal to check out the problems but do not change anything till you are sure where you are going.
