If you are having Lion problems, start by uninstalling Intego
DO NOT USE INTEGO VIRUS BARRIER WITH LION.
If you are getting Lion kernel panics, IVB may be the reason. I supect the new Lion indexing technology conflicts with IVB even though Intego say VB6 is Lion ready.
I just uninstalled IVB6 upon advice from a local Mac repair consultant. IVB6 is often in full time scan mode so its a constant factor. No other hardware or software issues. Eliminate the IVB6 factor and then see if reindexing, kernel panics and the other Lion problems people have go away.
I am suspicious of Microsoft Word 2011 as well, but I hope no IVB6 is the solution.
