Soon after launching Safari it starts to use 99-100% of the CPU which all but freezes everything. I've closed everthing I can find, but that hasn't helped. Are there open pages somewhere that I cannot see?

This has happened serveral times in the last few weeks, but usually clears itself up somehow.

HELP!!!

MacBook Pro, Mac OS X (10.7.5)

    Try troubleshooting extensions and third party plug-ins.

     

    From your Safari menu bar click Safari > Preferences then select the Extensions tab. Turn that off if there are any installed. Quit and relaunch Safari to test. If that helped, turn extensions back on then uninstall one a time to test.

     

    If it's not an extensions issue, try troubleshooting third party plug-ins.

     

    Back to Safari > Preferences. This time select the Security tab. Deselect:  Allow all other plug-ins. Quit and relaunch Safari to test.

     

    If that made a difference, instructions for troubleshooting plugins here.

    Anti virus software installed? MacKeeper?

     

    Remove all items from System Preferences > Users & Groups > Login Items

     

    Same for HD > Library > StartupItems then restart your Mac and try Safari.

     

    If that didn't help, open a Finder window. From the Finder menu bar click Go > Go to Folder

     

    Type or copy paste the following:

     

    ~/Library/Caches/com.apple.Safari/Cache.db

     

    Click Go then move the Cache.db file to the Trash.

     

    Quit and relaunch Safari to test.

    1) Confirm you turned off all extensions

    2) Confirm you turned off other plugins (this would include Flash)

    3) From Safari menu bar Safari > Reset Safari. Reboot your machine.

     

    If the problem persists, test in another user account. Same issue?
