I recently had to re-install my firewall (Zone Alarm), and have noticed that something like "an alternative Windows shell 32" (or similarly named), which I presume to be related toLitestep will periodically try to access the internet. I have been temporarily denying the access, and I have noticed that the Litestep isn't using lots of CPU resources. Not sure if this is a bug or a virus, but TrendMicro's housecall online scan and AVG Free do not find any viruses.
