I can probably answer...if you can define what a "bogus entry" might be...and tell me what log file you are referring to.
There are many startup items which should not necessarily be classified as such...but many of them are legitimate entries put there by programs which think that it's easier for the user if the program component runs at startup.
As for looking up anything on the Web...Google is still the #1 tool I suggest.
If you want to monitor/manage startup items, I suggest using a tool like AutoRuns for Windows - http://technet.microsoft.com/en-us/sysinte...s/bb963902.aspx
but I further suggest that you confine yourself to the Logon tab of Autoruns. That is the tab which lists the items users normally mean when using the term "startups."
