Survival Time for Unpatched Systems Cut by Half

UnderAttack writes "The Internet Storm Center published a graph showing historic trends for the "Survival Time" of unpatched, unprotected (windows) computers connected to the internet. Turns out, this number dropped from about 40 minutes last year, to 20 minutes this year. The survival time is calculated as the average time between reports for an average target IP address. If you are assuming that most of these reports are generated by worms that attempt to propagate, an unpatched system would be infected by such a probe. The data is collected from a large number of networks with different types of upstream protection. So if you are on an unprotected cable/DSL line, you may see probes much more frequently. Either way, 20 minutes is not long enough to download patches. The Honeynet Project did publish a paper with some stats back in 2001."

I wonder...

How much of the total traffic on the internet is from viruses/worms looking for targets? It's not that I really worry about getting infected, but I want to get all the bandwidth I can from my cable modem and I don't need rogue computer programs making the net crappier for everyone else!
