Recently safari will not allow a connection to a college website. This happened arpound the same that I installed sophos anti-virus. I removed sophos but it still can't connect. No firewall has been set . Any ideas?

MacBook Pro, Mac OS X (10.7.4), MBP 2012 model, time capsule

    Please read this whole message before doing anything.


    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.


    The purpose of this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:


    1. Be sure your Mac is shut down.
    2. Press the power button.
    3. Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
    4. Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).


    *Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, you can’t boot in safe mode.


    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.


    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.


    Test while in safe mode. Same problem(s)?


    After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

    Thanks for the help.

    I'm working this problem for my daughter in Ecuador. She reports that her macbook pro was able to connect with the college website at another location both on wifi and ethernet, so it appears her ISP at her apartment is the problem. The site is the only one she finds being blocked but it is the critical one for her to complete her online graduate program. The IT people who run the website in the US are baffled.

    If the ISP is blocking the site for some obscure reason, or if the site is blocking the ISP (also possible), she may be able to connect via a public web proxy or VPN endpoint.
