They probably advised you to uninstall it for a security reason that Oracle had yet to patch at that time. The 7u11 (Java 1.7.0_11 if you actually spend the time to run java -version in Command Prompt) install from Oracle's Java downloads page had the Ask toolbar stuff in it, so nope, it's not an issue of where you got it from. Then again, unfortunately, I'm used to dealing with this sneakware (hello Adobe? CNET? Yeah, the other posters above are right, they use it. A lot.) and never rush through installs (unless I know for sure it isn't there) since I'm a power user. I'm a programmer, and a developer. I don't just let programs install themselves and go along my way. I make it install how I want, then customize it a thousand times, and then use it. Hence, no crapware or sneakware has yet to hit my system. (Unless I really really wanted it, of course, which has yet to happen.)
Also, I'm a developer. Java is NEVER going to die. Why? For the same reasons C and C++ are still used decades after their initial development: many programs are written using them, and those programs MUST be maintained.
Java is used to run a lot of things. Client-side software, servers, you name it. At the rate it's going, there's almost ZERO chance for it to die or start fading from use anytime soon.
