I am running Windows XP SP 2. When my computer boots up in normal mode, usually right after I log in (sometimes after a minute or so), it gives the Generic Host Process problem and reboots. It lists a problem with my lsass.exe file. It works fine in safe mode. I have Trend Micro PC Cillin updated every day. Sorry for the lack of really specific information, this just happened a half hour before I had to go to work. I'll post more info once I get back to my comp. Thanks a bunch for your time and help.
