Thanks to all of you, I installed and have been using Sandboxie since Friday 9/7. A couple of months ago I received a panic phone call from daughter A. She was checking her emails on daughter B's work notebook and opened an e-card with the trojan/worm/virus or whatever was/is going around. Daughter B did have Norton installed (don't really know if it was up to date but it apparently did work) and immediately the comp went crazy with Norton and the malware firing away at machine gun speed, i.e. the malware trying to "reproduce" with Norton text boxes informing and stopping it. My question is: What would have happened if this had occured in Sandbox mode? Thank You!
