Windows Vista should have had an inbuilt antivirus program. it's not anticompetitive cuz vista already has a 2 way firewall and antispyware.

Windows/Vista should have been written/designed so anti-anything is not needed.

I think there are more eggs in the basket than that - why pick on MS. Viruses are of national concern. I am campaigning, in my country of residence, that the Government and/or ISP's should offer free downloads of Antivirus and spam controllers. They possibly even have the facilities to write the programs themselves.

I really disagree with the concept that others should be made responsible for the bad choices that some people make.
