I need to clarify, I didn't attempt to use download CleanMyMac, my scamdar went off as soon as I saw it. I couldn't get the window prompting me to download it to dismiss. There was an OK button which when clicked would simply re-prompt the message. It was a brutal cycle that I couldn't even open Safai Preferences, change windows, dismiss or hide, Safari 8.0 BTW was trapped by this malicious prompt to call for a solution.
Stephisa's suggestion:
But I managed to escape anyway by combining multiple techniques.
- First, quit Safari. To do this, press COMMAND, OPTION and ESC keys together to bring the Force Quit windows. Select Safari in the list and press the Force Quit button.
- Second: disconnect your mac COMPLETELY from the internet (WiFi, Ethernet cable, anything).
- Third: erase the following file ~/Library/Caches/com.apple.Safari/Cache.db
You can do this using
- (a) a terminal windows that you can find under the utilities folder in the application folder.
- Then type in the command rm ~/Library/Caches/com.apple.Safari/Cache.db
- (b) you can use the Finder window.
- Go under <your home directory> and then select Go-->Go to Folder (in the menu bar)
- Type in the following directory Library/Caches/com.apple.Safari and delete the Cache.db file.
- Four, restart Safari,
- Then close ALL Safari windows except for the main window (keep only one Safari window).
- In the Safari main windows, delete ALL tabs.
- Five, you can now restart your internet connection and continue browsing and have a normal life with ALL your money and pride intact.
Work perfectly for me, with a Shift+Open Safari I was able to beat the page prompt cycle and close the window out, but only after deleting the Cache.db file. Hope that clarifies.
