Maybe it is a idea to talk virus samples? Help people out with virus problems?
That's certainly one of the things we had in mind when we were planning through the beta; we thought people would want to discuss malware infections (of all varieties). Go for it!
As a side note, we added a specialized antirootkit engine a while back that was internally called VxMS. It's performed well in both internal testing and reviews, even against stand-alone rootkit scanners. Give it a go with NAV/NIS08 if you encounter a similar situation in the future and let us know about your experience. As you point out, rootkits can be exceptionally nasty and we've seen some unusual stuff in the past 12 months. There was one that created an EFS partition and dropped itself into it in order to protect itself from removal. Pretty darn clever but not undefeatable (though it did require an engine update).
