Protecting a System from Viruses
You can protect as system against malicious code and viruses. Memory is marked as non-executable
unless the location contains executable code. Some viruses attempt to insert and execute code
from non-executable memory locations; these are intercepted and an exception is generated. Your
operating system needs to support this option.
To protect a system from viruses:
1.
From the System Utilities screen, select System Configuration
→BIOS/Platform Configuration
(RBSU)
→System Options→Processor Options→No-Execute Protection and press Enter.
2. Select one of the following options:
