Ok I have a toshiba satellite with windows vista home premium 32 bit version and about 3 months ago I started getting this popup out of the blue that says "windows explorer has stopped working" the problem details say
problem event name: APPCRASH
application name: explorer .exe
application version: 6.0.6002.18005

Nearly always malware related, Have you run full system scans in safe mode
with updated antivirus and antispyware products?
