Yes, they appear the default settings. The scan is looking for all malware, which includes viruses, trojans, spyware, etc. etc. and the rootkit element is looking specifically for hidden items that may be rootkits.
In the Quick and Full System scan default settings the rootkit check is of a relatively low level, so I’m a little surprised to see this level of activity/depth in the rootkit scan. Have you changed the Sensitivity setting in either of the scans (see image1), Quick is set to Low and Full set to Normal. There are other settings in there and I’m not sure if any of these scan settings might effect the rootkit scan element.
I have set up and run a Custom scan (whilst replying to this) that just does a full rootkit scan on Thorough Sensitivity and that completed without any alerts, image2.
EDIT: I also setup and ran this scan on my win7 netbook and that also reported nothing. There have been two VPS updates so far today latest 111024-1 (these updates can also update engines), ensure that you have the latest update and run the scan again.
So I’m unsure what is going on with your scan, it needs some input from the avast staff.
