Issues with Windows
1. Viruses for Windows: tens of thousands, a large portion of which can still effect current versions.
To be fair, I use Windows 2k Pro at work. I do a auto download of the virus defintion file automatically every day at noon. Since I started doing that, I have had no problems with viruses. In the decad and a half I have used Windows, I have had two viruses, one troublesome to the IT stafff who took care of it.
