Windows Explorer.EXE Error Message for missing Root Certificate when computer is turned on

Question

After attempting to download some Microsoft updates.... on bootup my computer will display the following windows explorer.exe error message....

C:\windows\sys32\vsinit.dll  -- You are missing a necessary root certificate. 

As a result of this error message I have noticed that I can not copy or move any existing document files to any drive.  If I attempt to open a backup quicken file the computer program will shut down and I have  to restart the computer.  I have tried to download other Microsoft updates however they fail to install based upon the above error message.  I do not have the xp software disc, was loaded on the computer when purchased through HP, and I never created any backup XP software disks.

Any suggestions on how to resolve the missing root certificate error message to fix this problem.  Appreciate the assistance and thanks for any suggestions to resolve this issue.

Hi ronjul2,

Thank you for visiting the Microsoft Windows Vista Community site. The issue you posted is related to a third party program, ZoneAlarm, installed on your computer.  You may try uninstalling and reinstalling the software.  For the more information on this error, you may visit ZoneAlarm Support.

Using Third Party Software, including hardware drivers can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting from the use of Third Party Software can be solved. Using Third Party Software is at your own risk.
