Anti-Virus Software Prevents Boiler Safety Shutdown
|Event Year:||2001||Reliability:||Likely But Unconfirmed|
A TUV approved boiler safety protection system used Microsoft Excel on a PC workstation for programming. This workstation also had Norton anti-virus software running. The AV software prevented the proper communications between the PC and the protection system.
The protection system was incorrectly configured and a safety shutdown that should have occured did not.
