<p>when an access violation is detected. The main purpose of memory protection is to prevent a <a href="page.php?w=Process_%28computing%29">process</a> from accessing memory that has not been allocated to it. This prevents a <a href="page.php?w=Software_bug">bug</a> or <a href="page.php?w=malware">malware</a> within a process from affecting other processes, or the <a href="page.php?w=operating_system">operating system</a> itself.</p>
