Data Execution Prevention
Since I installed new IE 8, my computer will not run up internet explorer at all. The D.E.P. warning shows, and the program closes. I have tried restoring to a previous date but that does not cure it. I have also tried by the SETTINGS > CONTROL PANEL>SYSTEM>ADVANCED>SETTINGS, but again to no avail. Any idea what to do next? I have a paid up Trend security system so shouldn't have picked up any malware.

Re: Data Execution Prevention
Which DEP mode do you have your computer set up for? Have you restarted your computer?

Re: Data Execution Prevention
O.S. is Windows XP (SP3). Processor AMD Sempron 3100+, 1.81.Ghz, 960 Mb RAM, Microsoft Office 2003 (SP3), Works 7. Trend security system. All worked until I downloaded I.E. 8. I have done a restore to earlier without success.

Re: Data Execution Prevention
If you uninstall IE 8, it should revert to IE7 (assuming that was your previous version). Then you should be able to reinstall IE8.

Re: Data Execution Prevention
I have done both the things you suggest, the result is still the same - no I.E.

Re: Data Execution Prevention
Hmmm, this is an odd one. Although most folks don't need DEP if they have a good security defense established, and kept current, it is a good feature and it should be enabled, and IE should work fine if enabled so I don't why you are having problems.
So right now, when you right click My Computer > Advanced > Performance, Settings > Data Execution Prevention, how is it set? And right now, in IE under Tools > Internet Options > Advanced, under the security section, how is "Enable memory protection to help mitigate online attacks" set?
