I have Windows XP Home Premium & just yesterday started receiving "Program Not Responding" messages on shut down. At first it was ezSP_Px.exe, then this morning I also got it and Webroot Spyware not responding. Earlier in the day I updated all programs, scanned with Pcillin, Webroot Spyware, & Window Washer, ran disk cleanup and disk defragmenter. Before I did all that I hadn't been receiving the message. I don't have Symantec products on the computer. Anyone have any ideas? Thanks.
