A user reported experiencing a virus on their calculator after downloading a program, leading to the device becoming incapacitated. They sought advice on how to wipe the disk from their computer and reset the calculator. Suggestions included removing the batteries and holding the ON button for a reset, although the latter did not work for them. It was later revealed that the user had memory protection enabled, which prevented them from deleting the virus. After removing the backup battery, they successfully deleted the virus and restored functionality. The conversation also humorously veered into unrelated topics, such as the idea of household items needing software updates and the antics of a mischievous cat.
