Researchers Wonder Why Bagle Virus is a Success

Success of Bagle Virus Puzzles Researchers:
"Several new variants of the venerable Bagle virus visited themselves upon corporate networks last week, frustrating administrators and virus researchers who continue to wonder why these worms can still infect thousands of machines after months of warnings.
