One of these suggestions is sure to help you:
1] Run Antivirus software
Before you begin, scan your computer for malware.
2] Check Firewall related Services status
Having done that, Run services.msc to open the Windows Services Manager. Here you will have to ensure that the required services are set to Automatic and are started and running: In case they are not, change their Startup type to the type as mentioned above and Start the Services.
3] Use this BAT file
You may download and run this RepairW7FW bat (zipped) file. This is based on the information given in KB2530126. Once you have downloaded the zip file, extract its contents. Right-click on the .bat file and Run it as Admin.
4] Windows Firewall Troubleshooter
If this does not help you, run the Windows Firewall Troubleshooter and see.
5] Reset Firewall to default
One last thing you could try is to reset Windows Firewall settings to default and see if that works for you. All the best!
