PC Alert can be used for everyday communication, but it’s used best for emergency situations. Because it can pop through other windows and even through password-free screen savers, PC Alert is ideal for making sure the message can be seen. And because PC Alert can be disabled only by a system administrator, you can trust that any emergency (or everyday) message will reach its intended recipient.
