An illegal operation is a command that a computer cannot execute, causing an error message and potential program termination. Causes include memory leaks and overloaded programs. Data loss can occur, so regular saving and backing up is recommended. Multiple errors may indicate a system conflict, and repeating errors may indicate a virus or computer problem.
An illegal operation is a command that a computer cannot execute or does not understand. The computer will return an error to the user, alerting him that he failed to execute a command and that the program a user is running may be terminated by the operating system. Many things can cause an illegal operation. Usually people can resume normal activities after the error message appears, but sometimes the error can recur, indicating a more serious problem and the need for troubleshooting.
Processors handle a number of commands at any given time, especially when people run multiple programs. An illegal operation can occur when computers try to deal with memory leaks or receive nonsense commands from confusing or overloaded programs. The processor will tell the operating system that it was unable to complete an operation and the operating system will generate an error message to inform the user. It can also inform the user that the program will be closed.
When a program closes due to an illegal operation, the operating system will try to save the data, so when the user reopens it, he will experience only minimal data loss. Sometimes this is not possible. Regularly saving and backing up your data is a good idea to prevent catastrophic data loss due to system failure. If the program continues to experience errors, something may have gone wrong with the installation, or it may be conflicting with another program, plug-in, or driver.
If the illegal operation does not close the program, the user must save, note what was happening when the error occurred and continue working. If multiple errors occur, it can be a sign that something is wrong. People should think about the most recent changes to the system. Something like updating software, changing drivers, installing a new peripheral device, or making other changes could create a conflict. It may be possible to restore the system to fix the problem. People can also search the Internet for system conflicts to see if the problem is known.
Repeating illegal operation error messages when no apparent changes have been made to your system could be a sign of a virus or computer problem. A technical support representative can help you run some diagnostic tests to find out more about what is happening. It may be helpful to write down the details of the error message, including any error codes that appear.
