Hello together, the problem starts, after i found some "unknown devices" in the hardware manager. they all have the "eset_epfwndismp" in details. So i unstalled ESET, but the unkown devices remain after reinstall, but the firewall worked. So i found the ESET uninstaller tool. I followed the instructions: - Uninstalled ESET, rebooted. - Then rebooted to saved mode, used the uninstaller tool, deleted the ESET folders under roaming and local. - rebooted. The devices were deleted, i was happy... ... until i reinstalled ESET Smart Security 4.0... i got the error every time, that i should reinstall the firewall, which i did a lot of times, also i tried the new 4.2 versions with and without uninstaller tool, but nothing works any more. Every time i got the error with firewall malfunctioning. It said, that i choosed no filtering mode, which isn't true. I also tried some suggestions in the forum to use learing mode, but doesn't help either. So i give up now, don't know what more i can do. Any other suggestions? System is Windows 7 x64, ESET 4.0 german or 4.2 english, doesn't matter what i use.
