I hope I'm not missing something obvious. I have the dreaded searchweb toolbar at the bottom of my screen. Have run Adaware, Norton, Spydoc, etc. and nothing will get rid of it. What is this logfile data that people post? How do I post it? Thanks.

Sorry, I did not understand you precisely.
Therefore, my explanation could not achieve the goal.
First (before an analysis), you have to define the product to analyst and be sure that the product generates at least one type of log compatible to LogAnalytics.
Log file generating is under control of a product generating them. LogAnalytics is able to access log file generated by a product only.
If the product to analyze generates log, but LogAnalytics is unable to access that type of log, we could add the new type of log source to LogAnalytics.
If you want to analyze several products simultaneously, you have to configure correspondent number of log data sources (in LogAnalytics) for each the product separately
Unfortunately, I did not understand what you are going to analyze.
Would you specify the problem in more detail?
