F-Secure is offering a service which will send you:

information about virus attacks, denial of service and other critical security issue alerts to a wide range of devices, including mobile phones, PDAs and pagers

Not very innovative or anything but still a cool service if you ask me....although, imho, they should get the virus alerts out of there.  In most cases virus attacks can be mitigated by deploying a pro-active patch management policy from the get-go.  Which if your not doing please e-mail me at abaran[at]geekdojo.net when your network turns into a viral war zone and I'll happily fix it for thousands of dollars ;)
