Avast! Anti-Virus and/or FireFox don't seem compatible on USB

This topic was "bookmarks" ... but I feel it important to make more visible for users of U3 and Avast! to see. The issue is FireFox under U3 starts leaving behind tons of old temporary bookmark files like these (notice time created):

11/21/2006 09:28 AM 5,809 sessionstore-1.js
If you turn off Avast! AV (promoted at U3 site) this stops - but you'll still need to manually delete the old files.
I am guessing that FireFox fails to delete these temp files because when it tries to delete them Avast! has them open to scan. Thus perhaps FireFox just abandons them & never retries to delete them.
