• Name the area: 'Home Internet 1'. Use the firewall profile: 'Directly connected to internet'. Or if your Internet is setup to a router with other computers in your home pick 'Small home or office network'. Turn off Windows Firewall, it's not good to use one then one firewall on your computer. Or if you want to use the Windows firewall, disable the AVG firewall. But I recommend using the firewall that comes with your antivirus software eg. AVG.
• Hi would you take a sugar pill for an headache, so why are you using this rubbish for viruses. Go and buy a proper anti-virus software as this will cure nothing and may actually give you more hassle than enough.
• Well the question is not completely specified ......... In suggest you to reinstall AVG antivirus again on your computer........
