This worm is a medium threat in terms of its distribution, but in terms of the damage it can create, it's a more severe threat.

Our assessment of the worm damage is 'not serious'.

And we're working on another large distribution center there.

Why are the numbers so high today? IM is really growing in terms of use. Because of the popularity, it's a more attractive target to hackers and virus writers. The specific number of threats is not huge, but it's much more than the year before. So the percentage ends up being quite large.

IT departments have spent a lot of money on security. They've hardened the castle walls but left the drawbridge open with IM. The big problem is that IM is user-deployed.

The continuing trend is the increase in the growth rate of attacks. That trend has been consistent through the year.
