how to recover Safari from a browser hijack

Screen Shot 2015-12-10 at 13.32.39.png

The quickest way to get out of a persistent popup that won’t go away (unless you do what it demands!) is to quit or force quit* the browser then restart Safari holding down the ‘Shift’ key.

Holding down Shift allows Safari (or any other app) to restart without resuming its last state.

While this is a great, fast way to solve the problem, it can be annoying if you had other tabs open, and you don’t want to loose those too (or any unsaved data they may contain).

Here’s how you get rid of these kinds of Javascript hijacks without losing your other tabs.

1. Go to Terminal and paste this command (it’s all one line):

defaults write com.apple.safari "com.apple.Safari.ContentPageGroupIdentifier.WebKit2JavaScriptEnabled" 0; killall Safari

This turns off Javascript and quits Safari.

2. Reopen Safari
You’ll get all your tabs back including the hijacked tab, but the pop up won’t appear, and you can now close the hijacked tab.

3. Go to Safari Preferences and reenable JavaScript in the Security prefs
(alternatively you can do that in Terminal).
Don’t forget this step, or you’ll think the web is broken!

More sophisticated or persistent adware and malware attacks can be mitigated by using apps like my free App Fixer or DetectX.

*You can force quit an app by pressing the following keys in combination on your keyboard <command><option><esc> then choosing the app you want to quit.

news: App Fixer 1.2 released

We’ve just released App Fixer 1.2, available for free download from here.

If you’re not familiar with this junior partner in our troubleshooting suite of apps, App Fixer does a very specific job: it returns any app you select to its default preferences and settings with the click of a button.

It’s raison d’être is largely for those apps that get themselves stuck in some unresponsive state  (looking at you anything-Adobe). It also does a neat trick rescuing Safari from Adware on the side. ;).

If you’ve been using App Fixer already and you’re currently running El Capitan, we’re afraid you won’t see an update notice (the blame for that lies with Amazon AWS, but that’s another story). Just go to the App Fixer home page and download directly. We’ll be introducing an in-app updater (Sparkle) in the next release to make future updates more convenient.

 

 

 

how to block Flash in Safari

Safari Preferences Security

If you’re worried about news like yet another Flash vulnerability, the first thing to note is that Apple has moved to block all but the latest version.

However, given that exploits of Flash seem to occur sometimes within days of even new releases, it might be wise to think about blocking Flash altogether in your day-to-day browser.

Fortunately, that’s pretty easy to do in Safari. Just go to Safari’s Preferences > Security tab, and uncheck the ‘Allow Plug-ins’ box at the bottom. You can manage which websites are allowed access to Flash from the adjacent button, but an alternative strategy is to use a different browser (Firefox or Opera for example) for only viewing sites where you need Flash access.

Either way, its seems wise to make sure that Flash isn’t allowed unrestricted access on your main browser.
