I clicked on a news article about a pastor who died recently in Sacramento, and a malware popup for mackeeper.zeobit.com urged me to clean my computer. The malware shut all the other Safari windows. The pop-up had an OK button, but NO OTHER WAY to remove the pop-up or close Safari. The normal window controls were missing. All Safari Menu options were greyed out. I tried using the Apple Menu to Shut Down, but that failed as Safari refused to Quit.
As Safari would not Force Quit (greyed out) and would not Quit when I used the Apple menu to Shut Down, I powered off using the Power Button ...several times. No good - still had the non-closeable window and Menu options to Force Quit Safari or Reset Safari were greyed out.
I spent a long time using Chrome to read a lengthly Apple discussion, which ended May 28th. Not really up-to-date and no practical help. Finally, for no particular reason except for the passage of much time (30+ minutes?); when I next checked the Safari menu, the Reset Safari and Force Quit Safari options were no longer greyed out.
So I Reset Safari and Force Quit Safari for good measure. Now I'm afraid to reopen Safari. For now, I'm stuck using Chrome; and I don't care to use the Google product as it is basically spyware, IMO.
So, two questions:
1. Is there something I can do at the basic user level to prevent such interference that doesn't also cripple browser performance?
2. Is Apple going to do anything about getting these Mackeeper and MacDefender creeps from invading their browser? (Oh, I know you don't know... just venting... sigh... I mean, this stuff's been happening to people for many months, my software's up to date, i guess Apple isn't too worried about us little users getting freaked.)
