...i just thought something as big and popular as Photobucket cant be a risk,...
It never ceases to amaze me how people hoodwink themselves. The size and popularity of an organization means nothing. It's still staffed by people, and people often behave in stupid and inexplicable ways, sometimes in vast numbers. For example, millions put Microsoft software on their computers.
The Stock Exchange was serving this cr@p months ago, well before before Spotify, and apparently Photobucket, plus another 200,000 Websites were hoodwinked. In this case it's because they farm out advertising. They sell empty space on the pages that they deliver to you, and the advertisers fill in the empty space. In some cases the adverts are served from compromised servers. Oops. Only this morning a site owner asked me to turn off my ad blocking. Sorry, not a chance. My take on it is that it's the height of irresponsibility to send content from a third party to your users. There's just no way to satisfy yourself that it's kosher. Quite apart from the fact that it's extremely irritating for the users to be bombarded with adverts all the time.

You mean if you don't really expect it to work like a proper operating system?
Don't confuse the operating system with the user interface. Ubuntu basically uses the same operating system that many Linux distributions use, but the distributors of Ubuntu made certain choices about the way it 'looks and feels' out of the box. You can think of it as a commercial appliance with an industrial core if you like. I looked at it once, but being something of a control freak I found it not to my liking. I like to tell my computer when to mount a storage device, not have it happily announce that it's just done it for me without asking; and I decide what my networks look like, not some blooming network manager script. But on the plus side -- like anything which runs the Linux kernel -- Ubuntu is immune to all this Lizamoon stuff and a couple of million other Microsoft exploits out in the wild.
If you insist on running Windows, now might be a good time to turn off ActiveX, and to make sure your Acrobat Reader is up to date; and Java, and QuickTime, and the Office suite, and ... :yikes:
