Worm activity fell last month by over 80 per cent, according to research released today.

"Despite a lull in activity last month, we still warn companies that the danger of viruses remains ever present," said Charles McColgan, chief technology officer at Frontbridge.
"We continue to see new virus strains transmitted across our network on a daily basis."
