The operating system.<\/p>\n<p>Memory protection is a system that prevents unauthorized access to computer memory. It is implemented by the operating system, which controls access to memory by all programs. The operating system does this by assigning each program a unique address space, and by checking all memory accesses to make sure that they are within the program&#8217;s address space.<\/p>\n<p>Antivirus software can also help to protect memory by scanning for and removing viruses and other malware.
