Don't know what to make of Mac Defender?

Is Mac Defender a good product?  It showed up on my computer and asked me to register, though it seems impossible as it asks for a serial number of the product which I don't have

    My computer has been spontaneously restarting itself.  This last time I wasn't even at the keyboard, I was across the room.  I don't know what to make of it, completely baffled.  I'd love some help on this, and if it could come in layman's terms I'd love it even more.

    Hi ...
    Try Troubleshooting the MagSafe adapter
    If the Mac freezes, it may be a preference setting.
    Check System Preferences > Energy Saver
    See if Restart automatically if the computer freezes is selected. If it is, deselect that box.

  • Something keeps trying to download on my mac and I don't know what it is. It is not in the apple store and just comes out nowhere and request for my password to download something and I don't know what it is. How to make this stop?

    Something keeps trying to download on my mac and I don't know what it is. It is not in the apple store and just comes out nowhere and request for my password to download something and I don't know what it is. How to make this stop? It pops up every single day.

    Erica,
         I can, with 99.99% certainty, tell you that you are absolutely right in not wanting to download or install this "Helper," whatever it is (but we can be equally certain it would not "help" anything).
         I cannot comment as to Oglethorpe's recommendation of 'adwaremedic'; I am unfamiliar with it.  His links to the Apple discussion and support pages warrant your time and attention.
         It might be really simple -- Trying looking in your Downloads folder, trash anything that you don't know with certainty is something you want to keep, and then Secure Empty your Trash. Then remove the AdBlock extension, LastPass, and Web of Trust extensions to Safari and re-boot. If the issue goes away, still be extraordinarily careful in the future.
         Unfortunately, it's probably not going to be that simple to get rid of, in which case I'd then try the line by line editing in HT203987. 
         I have no further suggestions (other than a complete wipe and re-install...but that's a pain because trying to restore from Time Machine would simply ... restore the Mal).
       For the rest of us, please post when you find a solution.
         Best.

    Those are not viruses. You have probably installed some malware:
    The Safe Mac » Adware Removal Guide
    Helpful Links Regarding Malware Protection
    An excellent link to read is Tom Reed's Mac Malware Guide.
    Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.
    See these Apple articles:
              Mac OS X Snow Leopard and malware detection
              OS X Lion- Protect your Mac from malware
              OS X Mountain Lion- Protect your Mac from malware
              About file quarantine in OS X
    If you require anti-virus protection Thomas Reed recommends using Dr.Web Light from the App Store. It's free, and since it's from the App Store, it won't destabilize the system. If you prefer one of the better known commercial products, then Thomas recommends using Sophos.(Thank you to Thomas Reed for these recommendations.) If you already use Sophos, then be aware of this if you are using Mavericks: OS X Mavericks- Sophos Anti-Virus on-access scanner versions 8.0 - 9.1 may cause unexpected restarts
    From user Joe Bailey comes this equally useful advice:
    The facts are:
    1. There is no anti-malware software that can detect 100% of the malware out there.
    2. There is no anti-malware that can detect anything targeting the Mac because there
         is no Mac malware in the wild, and therefore, no "signatures" to detect.
    3. The very best way to prevent the most attacks is for you as the user to be aware that
         the most successful malware attacks rely on very sophisticated social engineering
         techniques preying on human avarice, ****, and fear.
    4. Internet popups saying the FBI, NSA, Microsoft, your ISP has detected malware on
        your computer is intended to entice you to install their malware thinking it is a
        protection against malware.
    5. Some of the anti-malware products on the market are worse than the malware
        from which they purport to protect you.
    6. Be cautious where you go on the internet.
    7. Only download anything from sites you know are safe.
    8. Avoid links you receive in email, always be suspicious even if you get something
        you think is from a friend, but you were not expecting.
    9. If there is any question in your mind, then assume it is malware.

  • Attempting to connect my MacBook to my 4s iPhone.  I have had them connected in the past to use the "hand off" function. Today it tells me "network unavailable"  make sure network access is enabled.  I don't know what to do.

    Attempting to connect my MacBook to my 4s iPhone.  I have had them connected in the past to use the "hands off" function. Today it tells me "network unavailable"  make sure network access is enabled.  I don't know what to do. I love the hands off feature as my iPhone is never with me when on my mac! I'm not sure what to do.  Both are "discoverable" via bluetooth and show up on each device but when I try to connect it says "network unavailable".  HELP!

    An iPhone will not pair via Bluetooth to a computer (Mac or Windows) except for personal hotspot and then only if your cellular plan supports it. https://discussions.apple.com/docs/DOC-7722
    If you are attempting to use Handoff/Continuity, that does involve Bluetooth but the devices are NOT paired; Bluetooth just needs to be on and the devices in range of each other. The following may help with Handoff/Continuity issues: http://support.apple.com/kb/TS5458

  • HT1349 I don't have a MAC, I have an HP pavilion a706n so I don't know what the serial number is. The HP serial number was accepted and neither was my itunes serial number. Does anyone know where to find the serial number?

    I am trying to find the serial number that is required by itunes for troubleshooting. But the trouble is, I don't know what it is.
    My computer is a HP (not a MAC). I have the itunes serial number. Before loosing my almost 5000 songs I was using an
    older version of itunes. I thought if I upgraded to the new version that I would get my itunes back. When I noticed the songs
    were gone was when I was taking saved items from my documents into a new 500G hard drive I bought yesterday. After
    loading a bunch of stuff it (not any itunes) I went into itunes and ALL of my songs were gone. What happened? What should
    I do? & Where is that serial number they are talking about?

    Hi Susan,
    Not sure why your post ended up in the Apple Server section but here goes.
    By default your music should be located in one of the following locations
    which you can see by clicking on My Computer
    Windows XP - C:\ - Documents & Settings - Username (your name or your login name) - My Music - iTunes
    Windows Vista/7 - C:\ - Users - Username - My Music - iTunes
    it's unlikely your music has been wiped and more likely that iTunes can't find the library file that tells it what music is in your collection and where it's located. This can happen if you renamed or moved one of the folders above to something/somewhere else. Another idea is to do a search and look for files in a format used by iTunes such as .mp3 or .aac which might show you where they are.
    Hope that helps
    Beatle

  • On my G5 mac at work, I am getting - don't know what to call it - looks like extraneous matrix type code around prompt windows and in applications. Sometimes I will get large shapes of colors, yellows, magentas, cyans. Anyone else experience this?

    On my G5 mac at work, I am getting - don't know what to call it - looks like extraneous matrix type code around prompt windows and in applications. Sometimes I will get large shapes of colors, yellows, magentas, cyans. Anyone else experience this?
    I will attach a recent screen shot of a print window I opened and the extra code is above and below the window. There are matrix type blocks of code and then lines under the window. I get this all the time and it is getting worse.
    Any help to get rid of it would be appreciated.

  • Transferring CS4 from an old Mac to a new one, I get a notice saying "licensing for this product has stopped working" Error 150:30. Don't know what to do? Thanks.

    I'm trying to migrate my CS4 from my old Mac to my new one. When trying to open photoshop, i get a message saying "Licensing for this product has stopped working." And "Error: 150:30" I don't know what to do from here. Can someone help me? Thanks.

    "Migrating" and/or "transferring" an application is not just asking for trouble but demanding it!
    Always install an Adobe application from scratch, from the original media: CD or download.

    My Mac Pro all of a sudden would not turn on. It beebs 3 times, pauses, and then does it again. I don't think I have downloaded anything recently and I don't know what to do!

    3 beeps usually means a Ram problem, have you added or removed Ram recently?
    And I will assume that you do not have a Mac Pro, but that you have a portable, a MacBook Pro.

  • I don't know what i need. I'am a mac user but i need to run quick books premier. This is the only software i need in windows 7. Could i have some advise in  what is better for me, Bootcamp or parallels

    I don't know what i need. I'am a mac user but i need to run quick books premier. This is the only software i need in windows . Could i have some advise in  what is better for me, Bootcamp or Parallels

    The Intuit rep said they don't "support" QuickbooksPremier on a "virtual machine." Do you know what I risk by using it, anyway? thanks for the advice about Boot Camp vs Parallels, BTW!
    I use QuickBooks Pro for Mac, so I haven't had need to try any of the Windows versions in a VM. But I can't think why it wouldn't work. From within the VM, QuickBooks Premier would believe it is operating on PC hardware within Windows.
    I would guess they mean that the multiple user support wouldn't work from within the VM. But I would think that would also work. Windows can see the Internet from within the VM, which means it can see your network. So if Windows can see the network, then QB Premier should be able to, too.
    I know you can get Parallels as a demo, and maybe you could get QB Premier as trial software. So if you already have a retail copy of Windows to load into a VM, it would only cost you time to test what's possible.

    HI ..
    Open a Finder window.
    Select your user account on the left in the Sidebar. It has a small house icon.
    Now open the Library folder then the Preferences folder.
    Move the com.apple.systemuiserver.plist file from the Preferences folder to the Trash.

    If you have a non-retina MBP then the noise is part of tye OSX startup routine.  It is checking the optical drive, and is nothing to be alarmed about.
