Yesterday in unknow reason my firewall end to work. Below scrren shot . Anyone had the same error and know the reason?? I'm using Windows XP SP3 (I'm using also Windows 7 beta but in Win7 everything is ok). http://img22.imageshack.us/img22/8991/erroresetss4sn7.png Edit: I tried to delete this files: C:\Documents and Settings\All Users\Application Data\ESET\ESET Smart Security. * epfwdata.bin * EpfwTemp.dat * EpfwUser.dat to restore default settings but didn't work. So I uninstalled SS and installed a RC version and everything is OK now .
