A friend gave me his infected, non-booting Win 7 PC. I thought this would be a good opportunity to try some repairs & learn something. After running Malwarebytes via Hiren’s mini-XP & removing Trojans & hijackers, the PC booted normally. But, the firewall is blocking & deleting all downloads as containing viruses. The message “Windows Firewall is not using the recommended settings to protect your computer” displays, but attempts to restore the settings failed. Microsoft Fixit unsuccessful. The “Repair Windows Firewall” tool was also unsuccessful. I did notice a Verizon file on the PC & verified that he used their internet service. I use cable internet, not Verizon. Now, I’m lost. Can you please tell me how to fix this firewall? Thanks.
