Almost always used in the present perfect tense. If you have been at something, it means that you have been working hard on something for a long time... or you've been trying to resolve something or find the solution.
2. Larry King has been at it (hosting his talk show) for decades. I think he'll probably kick the bucket live on Larry King Live.
3. I've been at it for a few hours and I can't seem to get rid of the virus on my computer.
4. Researchers have been at it for years, but still haven't found a cure for AIDS.
Isn't another important factor that you have not finished what you have been working on?
