Since March 16, I think after software update, my imac osx 10.7.5 can not display web pages (error: Safari can not connect to the server ...; same error with firefox). The mac is connected to the router via wi-fi, and cable. In the setting of my router tplink my mac is listed and has the ip address and mac address.
If I restart the computer with System Restore utility and try to navigate using the function 'search for help on the Internet' everything works. I ripistinato system osx lion without success.
I tried many solutions, but all without success someone can 'help me?

It's possible these are the problem - delete them from the startup items.
A quick Google search shows these as part of Peer Guardian. Do you have that installed? I seem to remember a thread where it was causing someone similar connectivity issues.
If you do have it installed, it's best to use the developer's uninstaller, if one is available. If not use AppCleaner that you obviously have.
