This one looks pretty bad. Distribution is gaining speed VERY fast, and not much is yet known about the virus. I had two copies in my e-mail before it even hit sarc or slashdot. Not much is yet known about the virus, but it has moved up to a level 4 threat level on sarc.com (which means that in the hour they knew about it, it moved to the same threat level as the top threats within an hour). Info can be found at: http://sarc.com/avcenter/venc/data/w32.nimda.a@mm.html http://slashdot.org/articles/01/09/18/151203.shtml http://www.datafellows.com/v-descs/nimda.shtml
