You appear to be running two (2) antivirus tools at the same time (NOD and Kaspersky) which could be contributing to the problems being observed (both used advanced heuristics). Please only run one at a time and disable (or uninstall) the other.

By default Data Execution Prevention is turned on for Windows programs and services only and for most users this is fine.

However, you can gain more protection by selecting the second option and DEP will now work for ALL programs and services on your computer. BUT this is know to generate some error messages as legitimate software can conflict with DEP.

If this happens, you get a warning dialog box on your screen informing you of an error and the software you are trying to use will not start.

If this was a nasty piece of software lurking on your computer then DEP will have done its job. BUT if it happens to you when trying to work with some software you fully trust, this can be a problem, but fortunately there is a solution...

...you will need to tell Data Execution Prevention to ignore the software you want to use!

(Note: The DEP error message should always tell you which software caused the problem and who the publisher is, if you do NOT recognise the information provided then suspect fowl play and seek the advice of a more experienced user/technician....)

Where Can I Find DEP On My PC?

1. On the My Computer icon right click with your mouse and choose Properties. (My Computer can be found on the desktop and/or the Start menu depending on how you have your Windows XP setup.)

2. A small window will have appeared called: System Properties. Look for the "tab" along the top called Advanced, now click it.

3. Now look for the section called Performance and click the button called Settings.

4. You will now see a new window appear called Performance Options, click the tab along the top called Data Execution Prevention and you should get the same window view as the image below.

Given the above, see if you can find a workaround to generate a Hijackthis log and post it here.
