DEP problem makes Web browsing difficult
Reader Robert D’Arcy is getting frustrated. Windows’ Data Execution Prevention is constantly malfunctioning and causing browser problems.
- “I use IE 11 with 64-bit Windows 7. The browser constantly gives me ‘Cannot open site’ messages.
“I repeatedly use a Microsoft IE fixit; it always finds that DEP is turned off and turns it back on. After that, my IE then seems to work for a while. But then the [error messages return].
“Everything I’ve read about DEP describes how to turn it off. How do you turn it on — so it stays on?
“I disengaged all IE add-ons (restarting the system, ad nauseam) and then enabled each one [sequentially]. But the problem persists. I’ve also tried to track whether any program I’ve used is the precursor — all to no avail.
“Any help out there?”
