Staff at hospitals across Sheffield are battling a major computer worm outbreak after managers turned off Windows security updates for all 8,000 PCs on the vital network, The Register has learned.
It's been confirmed that more than 800 computers have been infected with self-replicating Conficker code. Insiders at Sheffield Teaching Hospitals Trust said they suspect many more machines are affected but have not been reported to IT.
The Trust told The Register it now has the outbreak under control and is engaged in "clearing up" remnants. Non-urgent appointments in the medical imaging department had to be cancelled while its computers were disinfected. A Trust spokeswoman said no other direct impact on patient care was known.
