Dep errors in IE8 after NIS 2010 Update Install

I am getting DEP closings of IE8 involving Autocomplete after upgrading to NIS 2010. I get first a memory could not be read error involving autocomplete then in iexplore.exe followed by a complete closure of IE8 with a statement that this action was done be because of a faulty or malicious add on. I have shut down autocomplete in IE and browser protection in NIS and so far IE has been stable. I don’t know if all this is coincidental or is there a conflict between the two programs?  I am running WinXp Sp3.Thanks.
