Pulse/Virus defs seem to lately issued on an extended period basis. Normally issued 10 minute intervals, last few days had periods where this has extended to hours. This seems over the last few weeks to be more frequent. Contacting support no known problem, Manual Live Update says no updates required. 11th May, after 6 hours of no updates issued, Norton finally admitted server problem. About time this was fixed. Any body else with problem ?
