It was an add-on "given" to you when you updated Java, unless you carefully read and deliberately said NO to their generous offfer to redirect your default search engine.

You vigilance is always REQUIRED, and no software can protect you from things you agree to install and enter your Admin password.

It showed up on pages that required you to read and agree to terms. If you just clicked through them, you agreed to get redirected to Bing.

Java.com made money off your lack of vigilance. It was not an attack in the traditional sense.

There is nothing you needed to do. It was not an attack, and nothing was hidden on your computer. They just changed a setting because you said OK, possibly without your meaning to.

'That whole bing redirect issue' was not malware, and installing Symantec was not an appropriate response not that.
