"Not Gates' fault. Fault is with those who wrote the virus for illegal purposes in the first place."
LOL. The illegality may lie with thost who wrote the virus. Fault lies with those who created the OS that was so full of exploits, just waiting for a virus to be written to take advantage of the weakness.
Name an OS that has no vulnerabilities or weaknesses.
No, the ultimate fault lies with the Nimrods who continue to insist on using such a piece of swiss cheese software to maintain sensitive information.
I can guarantee this would not have happened on a UNIX system (pick your flavor).
