Don't worry Reba, Linux forgives you! :amen
You can install it side-by-side with windows or by itself.
You maybe should have help installing it just in case. I won't say Linux is without it's problems, and never have. Sometimes it's a tad attitudinal to install (at least with some of my older computers but maybe that's because I get cheap parts
), but once it's installed and working, it's intuitive to use, it works well over all, it does not slow up over time, and of course nowhere near the malware --- I have yet to even remotely have problems in that area.
If it's installed next to windows, you can still use windows for some of the
special programs, but use Linux for at least for the
basic (and more malware dangerous stuff) such as browsing, web sites (including online transactions), emails, office functions such as doc, spreadsheet and powerpoint type work, personal pictures, files and videos, and so forth. Linux also cleans malware off of the Microsoft part of your disk if you have any such viruses, and if the Microsoft does not boot, you can still use the Linux.
But I understand that there's some programs created only for Microsoft in spite of the vast choices Linux has, and if you have a few favorite ones, then keep the Microsoft for that --- there's no "sin" in that. But then quickly switch back to the Linux before the next virus gets ya! If you only want the Windows 8 for the basic functions I mentioned, then you don't need Windows at all and indeed are asking for trouble if you do.
