You have to ask if Windows and Microsoft software in general is fundamentally insecure. They have just announced that viewing an image can cause a virus to be installed on your computer! Deary me! A picture should never ever be executed! A picture should never ever cause any problems!
So here we are in 2004 after a good couple of years of Microsoft’s “Trustworthy Computing” initiative, and it’s dangerous to look at images on the web using Internet Explorer. I’m not sure I’d trust them with a tin opener and a can of beans…
Scary stuff though. Better keep that antivirus software up to date.
