Frequently when closing WinXP SP2, a popup window reads "Eset Nod32 antivirus. This program is not responding." With buttons to end now or cancel. This has been occurring only for the past couple of months and frequency is about 4 times a week. Quite annoying since I now have to sit here and observe every windows close down, else it will still be running in the morning. Any ideas for a fix would be appreciated. Using 3.0.636 with current data updates.
