Would this tax effect only people who use MS os's, or every single internet user, be it on linux, mac os x, cell phones, or anything else that is webcapable (tv's, fridges, even toasters?!!).
It sound rediculous really, currently most antivirus companies have problems keeping up with just windows xp, vista and 7, some do also do antivirus for macs, but thats not many. It would be near imposible to create an antivirus program for the many different linux distributions out there.
An internet tax isnt needed as we allready have one in the form of isp charges, and the majority of them allready do all the can to help out with security mesaures by offering free packages, offering tutorials about how to stay safe etc on the net. Its just not feasable and just sounds like a big money grab by MS. Not to mention that even if they were able to impliment something like this it creates one big target for hackers to target, and really helps them.
