please help

And the Microsoft fix for your growing MpKslxxxx problem?

Buta, again, I'm afraid your system will not run this program, even is the other issues are fixed. Is this autodesk program the ONLY program that crashes the system?

Our posts crossed.. the Ms problem could be fixed by deinstalling MSE and then fixing it:

After uninstalling MSE I ran a small programm "msecleantool". It gets rid of all registry entries that MSE unfortunately leaves behind. After rebooting I did a fresh install and since then had several manual updates. Problem solved, only one MPKLS entry visible!

You can find the tool at www.mshelper.de (a site by German MVPs, German language only, sorry) in the "Problem und Lösung" (problem and solution) section. Click on "Hilfe zum Entfernen von Microsoft Security Essentials" (help with removing MSE) to download the zip file.

For direct download just click

I hope this helps. Sorry for my English, I am not a native speaker

After reboot, download and install newest MSE version.

Great news! What was the last thing you did to fix it?
