Dag, a virus is not something that "terrorizes". A virus is something that replicates its own code. Something that just does destruction is usually called a trojan.
Looks like Windows could use some help here so I'll side with Windows.
Windows is a better OS because it's more usable. Linux is able to do more stuff, but everything it can do is very difficult to do. For example, try networking a bunch of computers in Linux. You'll find yourself reading the manual for hours just trying to figure out how to make it work. With Windows, just go to Control Panel >> Network Connections, then click on "Set up a home or small office network" and boom you're on your way. Do that to every Windows computer in the network and you setup a great network - easily. After that, try to setup a network drive. In Linux, you're back in the manual reading how to do it. With Windows, open Windows Explorer, go to file >> my network places >> map network drive. Just browse to the shared folder you want mapped as a drive then click OK.
Now try to setup a network printer. With Linux you're back reading the manual. With Windows, go to Control Panel >> Printers and Faxes >> add printer, select network printer, and it will display all detected printers on computers in the network.
Windows is better because programs can be installed by just double clicking. I download a file, I double click it, it installs. With Linux, I have to try to compile the program before installing it. Most of the time, compiling it goes smoothly, but sometimes you'll get errors saying you are missing dependencies. So then you go to download the dependency. When you try to compile it, it says you are missing another dependency. You get the other dependency and it needs another one. When I tried to install WINE on Mandrake 8.2, I had to track down 4 different dependencies. The fourth one I got (which was needed by the third one), wouldn't even compile properly saying my version of GNU compiler was wrong. I got an error that said something like "your version of GNU is 2.2, Bison will only compile on version 2.2". Well that's just great, a program that says I have the wrong version but the version I have is the only version it will work with.
That was the same day I formatted and put Windows back on.
Windows is better because each version of Windows is basically the same. If I download a program and try to install it, it will work no matter what version of Windows I have. The problem with Linux is that each distro is slightly different. The Dev folder may be in a different place, some lib folders are here instead of there. It's minor differences between distributions that make it impossible to release program as self-installing files. Some programs are install files such as OpenOffice or Mozilla, but at least 90% of the programs for Linux must be manually compiled. As said before, compiling doesn't always work.
Windows is better because people are more willing to help you when you have a problem.
If you go to a Linux forum like LinuxQuestions.org, you'll notice a lot of people saying "just RTFM" and not offering any real help. When people post questions about Windows, it's very rare that somebody replies RTFM.
I'll post again when I've thought of some other things to say
