PC Security question regarding dual Linux and Windows operating systems
I have been considering adding a Linux OS to both my laptop and desktop PCs, so that each has a dual operating system, with the intention of using the Linux OS while browsing the internet and the Windows OS when I need to use programs incompatible with Linux. What I want to know is whether doing this would really confer any advantage to me in terms of reducing the likelihood of picking up some form of malware while browsing. After reading a Myth Busting discussion from last year about whether or not Linux machines are immune to them, I now have doubts about it.
The reason I am considering it is that I have had two severe malware infections on my Windows desktop within less than a year -- the first one completely destroyed my hard drive, resulting in the loss of several very important files and the second one totally blocked my use of it, leaving only the Safe Mode with command prompt functional. I'm having to copy needed files individually in this mode -- a very time consuming process! I don't want this happening again, which is why I am considering Linux, but I also want to be able to continue to use certain of my Windows programs. I came across information to the effect that you can have both OSs and switch back and forth between them if needed. But now I am wondering if a dual system would still leave my machines vulnerable, so if anyone can shed some light on this subject, I would really appreciate it!
