An interesting issue
Not a lot of help but if it wasn’t for the error message you’d still be in bliss
(that’s a not knowing bliss)
File path appears to be:
C:\Program Files\NTRU Cryptosystems\NTRU Hybrid TSS v2.0.7\bin\tcsd_win32.exe
I don’t have that on my desktop (WXP OS) but haven’t checked notebooks – yet
Since already Google searched you've probably seen a number of Dell notebook users reporting same problem, without any confirmed fixes
There was a similar query posted click here, unfortunately no feedback
If not already seen in your Google search:
Read this a very intriguing detective story about silent black helicopter chips
The guy didn’t seem to get anywhere with Dell
Have you tried Dell Customer Tech Support?
Security software (in particular AV software) does tend to hang on during Windows shutdown & maybe tcsd_win32.exe is causing the AV running in the background (memory), shutdown problems?
Only positive test would be to first disable Symantec Client Security 3.1 & see if message appears
If error reappears then you would need to uninstall & recheck
Try this solution. Add The embassy suite software in your Firewall exceptions.
Location of file is C:\Program Files\Dell\Embassy TrustSuites By Wave Systems\Embassy Trust Suites\EMBASSY Security Center\program files\Wave System Corp\EMBASSY Securiyt Center\
File name = EmbassySecurityCenter.
Once I allowed this program. Error went away when I shutdown the laptop
