I upgraded to the latest version of Firefox 3.0.1 today on a couple of machines. Since then every time I start Firefox, a few minutes later WinPatrol alerts me on a new hidden file which is always in C:\Documents and Settings\myname\Local Settings\Temp\etilqs (followed by random numbers and letters and changes with every restart of Firefox). I'm pretty sure it isn't malware but does anybody know what function this file performs? Running Symantec corporateV10 and GeSWall paid. Thanks!
