I finally got back onto my Buzz page, so will share my experience just in case there are others out there in the same predicament.
I first ran Norton and then a malware program. Didn't help. Then I tried going in on Firefox and got in! Then, I tried another computer with Internet Explorer 8 on it and got in. So, I upgraded my Explorer and the problem is fixed. Why Explorer 7 worked until just recently, however, I don't know.
Anyway, problem solved.
