Computerworld has an opinion piece by Michael Gartenberg suggesting that business users carefully consider a potential switch from Internet Explorer to Firefox, since Firefox doesn’t run Microsoft ActiveX code. While some businesses use ActiveX controls, ActiveX is still the primary distribution mechanism for spyware and viruses.
I have used Firefox in various forms for over a year now and have had no problems. I am still forced to use IE for some things like Sharepoint, but these are few and far between. The cost of scanning for viruses and spyware, keeping current with updates, and fixing the inevitable problems caused by IE just became too high for me. If business users start adding up the real total cost of ownership of fixing all of the problems inherent in IE, they would be concerned as well. How many hours did you spend scanning for, and removing spyware this year?
I also find Microsoft’s Anti-Piracy plan somewhat ironic. Microsoft plans to stop pirated copies of Windows from downloading patches and security updates. Had Windows been written with security in mind, then people would not require the updates that Microsoft wants to prevent them from downloading.
