I just installed the trial version of NOD32 on my ThinkPad X60. I was using AVG, which I removed prior to installing NOD32. When I boot the machine, it's not responsive for a period of time after the desktop is displayed. When I shut down the machine, I get messages stating that certain services or processes have not yet terminated and asking if I want to end them now (at the risk of possibly losing data). The processes/services vary. I suppose that NOD32 is scanning the processes/services during bootup and shutdown and that this is creating the delay, but I wonder if there is anything that I can do to fix this. I haven't had this happen with any other AV software I've used.
