Employee infects council IT system
A computer virus crippled Ealing council's computer system for several days after the memory stick was plugged in at its housing department in west London on May 14.
A council report states: "At the point the memory stick was plugged in the virus attacked the host PC.
"It blocked connections to anti-virus and Microsoft Support websites and attempted to establish connections with 500 internet sites chosen at random from a selection of 25,000 seeking instructions from its author, and sought to also contact other similarly infected PCs that it could find. It then started propagating itself across the Ealing network."
