You got the bug report...half right. You need a bit version of both Win7 and Java, and you need to post a launcher/error log. Also, I'd get rid of McAfee if you can, and go with something free that works better.

I have the same problem but then offline, I open my world and then it works for 5 seconds after that major lag shows up and after that, everything just freezes and wont react.
