HT201276: Force an app to close on your Mac

Q: I went to the Obama Care health enrollmentsite and my computer suddenly went to a white screen and kept blinking.  It acted as if it had a virus.  I could not shut it down and finally had to FORCE QUIT.

I did a quick Google search to find the health care enrollment site.  I typed in obamacare enrollment, landed in what looked like a credible site and suddenly my computer acted as if it embarked upon a virus.  the screen went white and started blinking...acted as if it were extracting something.  I tried vigorously to shut down and could not.  Eventually I was able to force quit.  Hopefully all will be well when I turn it back in tomorrow.  Be careful!

    It sounds like you probably clicked on one of the ads that shows up when you use those search terms. The top "match" given by Google when I tried that was an ad for a site at obamacareusa[dot]org. This is not an official site, and clicking one of the links resulted in an endless swarm of new blank windows being opened. Although I would not trust anything on this site, you should be fine... At this time, there's no known Mac malware able to install just by visiting a site. As long as you did not download and install something from this site, there's no malware involved, just a high likelihood of a scam, which it sounds like the broken site prevented you from falling for.

     

    The real site is:

    While "Obamacare" is a very commonly used slur originated by the GOP, and has made it's way into every news service and newspaper, it's not the name of the bill which was passed. It's the Affordable Health Care Act.

    Thomas: I left a message for you in the Lounge. Could you take a look at that one, please? If may be buried back a page or two now.

    Thank you.  Although, after having turned off my computer, when I log back in and click on the Safari browser the site and the swarms of blank screens appear again and I am unable to shYT it down w/o force quitting.  Thus, I am using the Firefox browser.  Any advice on what to do to be able to use my Safari browser again?  Thanks.

    Force quit Safari again, if you have it open. Then hold the shift key and relaunch it. That tells Safari not to load any web sites from the previous session.

    Actually, looks like the site did cause some damage.  I just noticed that my sound isn't working.  I went to a YouTube site to play a video and there isn't any sound.  I put headohines in and it still does not work--help?

    Greenlife:

     

    Applications > System Preferences > Sound > Output Tab

     

    Get an old DVD/CD and put it into the machine.  The media should play and sound should come from it.  Or play something from iTunes.  Remember to use the buttons for the sound on the keyboard to test as well.  If you do not get sound at this point perhaps a driver was tinkered with and I would suggest the Apple store as they can fix this quicker then any other means.  If you do get sound and the browser is at fault, check the youtube playback settings to ensure that sound is turned up and is not muted.

     

     

     

    Truth

     

    It sounds like the web has gained access to things it shouldn't on your machine. If you have a tech savvy friend I would take the computer to them and tell them that you were attacked by malicious browser websites.  Identify which software you were using when this happened.  There may be various residual issues outside of what you are experiencing now.  Although MAC is better then most, it is not impervious to the web.  Sadly the company does not acknowledge this.   If a friend is not an option your best bet would be the apple store.  Again, the simple issues you have mentioned do not mean that you are clear form malice.

     

    If I have this issue and I am using a non standard browser like chrome or firefox I backup my favorites and do a scorched earth policy of removing the offending application and its files and then reinstall it.  This does remove any saved passwords etc and history but it also removes any unknown content that could cause issues.  In theory safari should be safer to use when "privacy" is turned on.  Sadly technology like flash and pdf reader now allow for unsafe conditions to a computing system and cannot be trusted.  And these are said to be the more safe plugins to have installed to your web browser.  Even the bank vault is insecure if the door is wide open.  Plugins although useful cannot be implicitly trusted.  You machine is only as safe as the most insecure software installed to it.

     

     

     

    Treating the symptoms does not prevent the cause

     

    The only effective way to protect yourself I know of is to use an enclosure around the web browser and trick the system to believe that it has access to your computer. Rather like the reverse of the WW2 bomb shelter. VM-Ware, Zen, Virtua Box, all allow for operating systems and web browsers to be installed to a Virtal Machine (VM).  By running the PC within a PC and only using it for web browsing the only thing that can be damaged is the virtual machine (VM).  Since virtual machines (vm's) are nothing more then files on your computer they can be copied, deleted, and moved.  Completely eliminating or vastly slowing down the ability for a virus or malicious site to infect your machine.  This method allows you to use any operating system and any web browser you need to access the web. 

     

    By optimizing the VM and removing everything but what is needed to run the web browser you can get down to a smaller file size for the virtual machine and need not use 10GB.  Once the VM is created configure the operating system and web browser to a point where you feel that it is useful and shut down the VM. Then look on the hard drive  for the large file and compress it to create a copy/backup.  Now when ever the browser is compromised in the future you can simply delete the VM file and uncompress the backup into the same location as the VM file you just deleted.  Never taking more then 10 minutes of downtime, ever.  Norton Ghost used to be my tool of choice in the Windows PC.

     

    I am not suggesting that this is fun, but when you consider how many days this current inconvenience is costing you in time. 10 minutes reset time is irrelevant. Get the proverbial cup of coffee and talk to your office buddies giving yourself a 10 min work break, come back and everything is as it was before.

    Thank you.  I went into the apple menu-settings and found that the internal sound from the computer was not highlighted as before.  I highlighted it and the sound came back on...will take my MAC to the Apple Store to check for residual.

    I'm sorry, but that's simply not the case. Simply browsing to a particular site cannot infect a Mac with any kind of malware at this time, and certainly cannot allow the site to access things on the computer. There have been times in the past when this has not been true, but always in relation to third-party software that modifies browser behavior and opens widespread vulnerabilities - notably, Java and Adobe Flash Player. Currently, all vulnerable versions of these things are disabled, if installed, by Mac OS X, and neither is installed by default.

     

    Disagree? then constantly browse the dark side of the web and you will understand.

     

    That's what I do. I track and research Mac malware and adware. So, I do understand that even though there's a lot of nasty stuff out there, the only way it can affect your Mac at this time is if you actually manually open something that gets downloaded from a bad site.

     

    Of course, it's always wise to be cautious... but the proper solution for the average Mac user isn't to run the web browser within a virtual machine, it's to avoid the dark side of the web entirely.

    As Thomas has noted. Not possible. Not even a little. It's the same as pop ups that claim to have found numerous infections on your computer and you need to call the Microsoft help desk NOW, NOW, NOW!!! - Literally, 100% impossible. There's no software of any kind that can detect what's on a remote computer through a web browser. They also can't change settings, detect adult content on your computer, etc.

     

    If light man were talking about Windows, then yes, there's all kinds of nasty stuff out there there that can affect a Windows computer with its Swiss Cheese OS just by visiting any of thousands of nefarious web sites. There has to date been only one such attach on the Mac OS, and it was a workaround using Java (not JavaScript) to automatically cause a site to install malware on a Mac. That was patched over two years ago and any Mac using a fully updated Snow Leopard and forward Mac OS is no longer vulnerable. On top of that, Apple doesn't even install Java with the OS anymore, and hasn't since at least Mavericks.

     

    Not knowing everything you did during the pop up storm, I can't say for sure why your sound got turned off, but I guarantee it didn't have anything to do with any web site.

    Thank you.  Actually, I did nothing but force closed the site several times.  The next day I went to Youtube and noticed that the sound was off.  I do have Java installed to use as an interface for access to Class Live Pro software.
