You installed the latest Symantec Event Manager (SymEvent) update on your Windows XP computer. When you restart the computer, you see a blue screen with the message:
ErrorMessage: IRQL_NOT_LESS_OR_EQUAL STOP: 0X0000000A (0X0000000B,0X00000002,0X00000000,0X804EA7AB)
This was caused by a problem with the downloaded update file. The problem has been fixed, and a new SymEvent file is now available through LiveUpdate.
To resolve this problem see Symantec Knowledge Article: Error: "ErrorMessage: IRQL_NOT_LESS_OR_EQUAL STOP. . ." occurs after installing the Symantec Event Manager Driver on Windows XP (In English)
