I don't know any statistics but I would say that the number 1 problem here is Windows and the almost-mandatory need for an antivirus they are trying to enforce. So on one hand you have a widely-used but broken product (Windows) that needs another usually costly product (the antivirus). Both need to be kinda up-to-date in order to have this run smoothly and virus free. So I'm not certain the government could just "vaccinate computers" (by upgrading Windows/antivirus): just think of the user-level applications incompatibilities. But the governments might think about what does it mean to have a critical global infrastructure product that depends only on one (foreign) company: Microsoft. I wouldn't like that... So while nationalizing stuff doesn't sound really nice, perhaps the government(s) should start defining some regulations on the quality of Windows as well as a control body. But this is an even less reliable, corruption-sensitive, bureaucratic situation. In the end perhaps it's best we leave things the way they are.
