Understanding Data Execution PreventionData Execution Prevention (DEP) helps prevent damage from viruses and other security threats that attack by running (executing) malicious code from memory locations that only Windows and other programs should use. This type of threat causes damage by taking over one or more memory locations in use by a program. Then it spreads and harms other programs, files, and even your e-mail contacts.Unlike a firewall or antivirus program, DEP does not help prevent harmful programs from being installed on your computer. Instead, it monitors your programs to determine if they use system memory safely. To do this, DEP software works alone or with compatible microprocessors to mark some memory locations as "non-executable". If a program tries to run codeómalicious or notófrom a protected location, DEP closes the program and notifies you.DEP can take advantage of software and hardware support. To use DEP, your computer must be running Microsoft Windows XP Service Pack 2 (SP2) or later, or Windows Server 2003 Service Pack 1 or later. DEP software alone helps protect against certain types of malicious code attacks but to take full advantage of the protection that DEP can offer, your processor must support "execution protection". This is a hardware-based technology designed to mark memory locations as non-executable. If your processor does not support hardware-based DEP, it's a good idea to upgrade to a processor that offers execution protection features.Is it safe to run a program again if DEP has closed it?Yes, but only if you leave DEP turned on for that program. Windows can continue to detect attempts to execute code from protected memory locations and help prevent attacks. In cases where a program does not run correctly with DEP turned on, you can reduce security risks by getting a DEP-compatible version of the program from the software publisher. For more information about what to do after DEP closes a program, click Related Topics. How can I tell if DEP is available on my computer?To open System Properties, click Start, click Control Panel, click Performance and Maintenance, and then click System. Click the Advanced tab and, under Performance, click Settings. Click the Data Execution Prevention tab. NoteBy default, DEP is only turned on for essential Windows operating system programs and services. To help protect more programs with DEP, select Turn on DEP for all programs and services except those I select.
Have you got SpyBot S&D? That's pretty good at rooting out naughty adware & spyware stuff. And it's free.You can get it ...sorry, you cannot view external links. To see them, please
REGISTER or LOGIN. Just scroll down til you find it.
There could be something nasty going on, but another possibility is that there's just something above board happening which is "incompatible" with DEP.Did the messages start after you'd knowing installed something, or perhaps downloaded automatic software updates for Windows (Windows Update, Acrobat Reader (you should be on ver 9.1 by now), Adobe Flash etc etc?
If you want to see DEP as protecting your computer it's to late by then. You installing a program gives it administrative rights and 'access' to your system. ...To be honest I'm not really sure what DEP is seen to protect? If you have a root kit DEP probably won't notice in any way. If it is a virus then it's already there, in your computer and will probably write itself to all your executional code like *.exe *.com files, etc etc, not caring for what DEP will do or not
