You have to check that your Anti-virus is registered or not. If not then buy its premium membership or download the registered one, after registration. Update it to latest version. So it can work accurately.

Try to update the previous or the best thing is that uninstall it and download latest version and make sure that your system supports the latest version. Other thing is that there might be some file corrupt or some virus is there which is resisting the running of your program so try to scan your computer and repair the windows and other files.

Do this in normal mode or the best thing is to do it from safe mode. Secondly check that Have you tried to access the WAN address or LAN address of your system?

Any LAN address will never be accessible from the outside of the LAN of your system; you are also familiar that now most of the networks are alike so you were probably trying to access something during the work. There might be another reason that your WAN IP have some other address or subject so you must check that.

Or you can also use the service of DNS which is dynamic in nature.
