Using on old Mac mini - intel i5 and Safari takes an age to load or do anything useful. Today had interesting address/text appear in safari after the history/java caches had been cleared, a fresh boot and Safari opened with a new page which had 'Honest John' in the address bar before going blank. Also after a fresh boot the monitor/video reboots itself now for no reason - ie. goes black with energy star logo as if it has been switch off and then comes back on? Safari also takes an absolute age to warm up and become useful and isn't running any extensions. Could I have some spyware of a virus?
