Gosh, thanks for such fast reponses, you guys. The program is turbotax2010. I no longer need it. I normally don't have trouble installing anything with Avast running, but when I tried to uninstall using the control panel, I got a message saying the "directory" was full, and to turn off Avast, which might finish the uninstall.The uninstall had proceeded to its finish when the message appeared. Is this helpful?
