Data Execution Prevention

What software was installed?

DEP prevents malicious code from executing from protected areas of memory.
Something you installed, or that piggy-backed its way in the installation,
is trying to run on your machine.

Hi,

Have you tried contacting Pinnacle yet? There are several patches for vers.
9.

Not quite: DEP prevents code from executing from data areas of memory.
It has no inherent notion of "maliciousness".

Or something is simply breaking the new rules that DEP applies. It's
poor programming practice to run code in memory allocated for data,
but it's only become a crashing offence post-DEP. Some programs do
this for no good reason, while others do this as the chosen way of
what it needs to do - av often falls into the latter category.

Google(SP2 DEP {NameOfSoftware} )

At the level of abstraction it operates on, it can't be expected to.

Or... are you advocating "Trsuted Computing" at the hardware level?

DEP is like PnP; it will be wobbly at first, but will grow into
something stronger, more reliable, and pretty well indispensible.

Unfortunately, there's no way to get to there from here without going
through the teething issues. It will be worth it though.

If you can DEP, then do - it will harden the PC so that a lot of raw
code exploits will bounce right off. Much like using Eudora for
email, with the "use MS Viewer" disabled, lets one just laugh at all
the OE/Outlook/IE exploit panics.

Hi Chris,

I was over-simplifying in my explanation for the sake of expediency. My use
of the word 'malicious' was to convey a sense of foreboding, not to
qualify/categorize the type of software that executes from the data areas of
memory. DEP doesn't categorize, it simply prevents anything from executing.

This is likely the case, which is why I referred the OP to Pinnacle support.
There is a flaw somewhere in the program that is causing this.

Truer words were never spoken.
