smlogsvc.exe is not running
the file is a windows service required for loading 32bit performance counters on a 64bit os
Performance Logs and Alerts service - Windows 2000/XP/2003. This background service collects performance data from local or remote computers based on scheduled jobs and either writes that data to specific log files, or it triggers an alert, or it does both.

my case - it is running in the forefront, not in the services section, its instances, and compatibility with windows general component access/management, makes it particularly dangerous, my sense is that some may be using it as a "springboard" -my term, thought logs and alerts are helpful sometime, so thos one is a difficult question, it's rather easy to "stuff" a virus to make it look similar in size, so what does that mean?
