Windows 7 – Fix Windows Explorer Crashes When Copying Files

windows 7windows-explorer

I have Windows 7 (64bit) and since a few windows updates the following error occurs: When I try to copy a file from one directory to another with the explorer, windows tells me that the explorer hast stopped working. After a few seconds the explorer restarts and works fine until I try to copy something again. Most other operations of the explorer work (e.g. delete, rename, new, open with etc.). None of the solutions I found on the internet work, so any idea to fix it is appreciated. Thanks in advance.

More information:

Specs: Windows 7 Home Premium SP1 64bit (Version 6.1.7601 Service Pack 1 Build 7601), i5 cpu, 8gb ram, 1,36 TB HDD (ST31500341AS), usb keyboard, 2x usb mouse (cable+wireless), GeForce GTS 240 gpu (ask if you need more)

Antivirus: Norton Security

What I tried: Disabled shell extensions, disabled all third party services, registry cleanup, checked harddrive for damaged sectors, defragmentized harddrive, virus scan, ad/malware scan, system file scan

Looking at the crashdump with Windbg.exe (which is part of the Debugging Tool for windows/Windows SDK) shows that psdprotect.dll from EgisTec MyWinLocker 3 causes the crash:
