Data Execution Prevention, or DEP, raises an exception if it detects code loading from the default heap or stack. Since this behavior is indicative of malicious code (legitimate code does not generally load in this manner), DEP protects the browser against attacks rendered, for example, via buffer overflow and similar type vulnerabilities.
DEP was first introduced in Windows XP Service Pack 2. Follow the instructions below to enable DEP in Internet Explorer v7.
