Software: Windows 7, 64-bit, SP1, + latest updates from 'Windows Update' Hardware: - HP Pavilion dv7-6b76eo notebook PC - Intel core i7 2670QM - 8gm ddr3 RAM, Samsung - Upgraded to Samsung 850 Pro SSD 256gb where OS is installed -Have blocked the discrete AMD GPU in BIOS so only running with the on-board Intel GPU Issue: Installed the Private firewall and it causes my Win7 to freeze immediately after the reboot. Luckily I have a multiboot setup with Win10 installed on a separate partition. Others are having similar issues with the firewall, too, as I've read. So I remedied things from within Win10 by deleting the firewall folder in C:\Prog.Files in the Win7 partition. Then back to Win7, uninstalled Avast, stopped Windows Firewall, cleaned registry and temp files and everything with CCleaner and YourUninstaller, rebooted 19 times and once that was done I tried to install the Private firewall again, but in vain, same issue again & again... tried a couple of times. I get no error code, nothing. Just my screen freezes. The freeze happens after I install the firewall and then of course I have to reboot. So I reboot and when I enter my user account password and enter Windows, my start-up items start loading (as usual) and at that moment a window of 'Privatefirewall' appears in the middle of my screen, but the window does not respond. It's frozen as well. So it stays like that for a bit and then my whole system freezes. Again and again. Cleaned everything I could think of, installed it again and same issue happened. And prior to the following few attempts to install the firewall I had disabled both Windows Defender and Windows Firewall in Services.msc. Then rebooted and then tried to install again the Privatefirewall. No luck. As mentioned, I have a multi-boot setup and my ssd is partitioned so that on 2 separate partitions I have Win7x64 and Win10x64. So, as I said, the problem with freezing happens on my Win7x64, but right now I managed to successfully install Privatefirewall on my Win10x64. No problems over there at all. Help pls! This firewall was recommended to me as the best out there. The best and only one allowing proper control, which is what I need.
