new and unknown user account - pirate being?

I have a MacBook Pro, on which I recently installed OS X El Capitan. A few minutes ago I had to force a shutdown down because my MacBook does not have answered what anyone more. When I restarted, I saw a new user account, that I have ever created. My macbook has been hacked? How can I remove such account unknown? I am concerned that at some point, it asked me to put my password to iCloud and other Apple ID - which I did not. Help would be very appreciated be! Thanks in advance

Unlikely, it was hacked. Go to System Preferences > users and groups, and delete the new account. Then please download and run EtreCheck, created by one of his own assistants here in CSA. It is a diagnostic tool that is very useful for us to find problems. It will also give us additional specifications on your Mac. After his execution after the logfile here.

The account unknown S-1-5-21-98... user id internal to the user account that created the file and so you have the permission of that user, which is impossible because even if you create a user account with the same name, the user id cannot be the same.

  • Homegroup and multiple user account problems

    I have been searching the net for information and can't find anything that matches.  I'm having all kinds of problems through the homegroup and multiple user accounts.

    I would like to know: when a machine (laptop in this case) is off the network, the individual user accounts will remain visible under homegroup?

    If they are not, then homegroup is not for me.

    UPDATE and closing:

    I confirmed that the individual accounts of the user on a machine that visible to another when this computer is connected to another group residential computer on a local network domestic.  Why they don't look just like a homegroup internally I don't get except that the machine would always be part of a group residential e.g. a laptop, as in my case, would be carrying a homegroup with it and not be able to jump on another residential group in a different location.

    What was causing me a lot of trouble has AVG Free.  Attention, the installation of AVG Free homegroup PCs cannot meet or is inconsistent at best.  My laptop would show the user accounts, but not the other homegroup PCs and both could indicate that there is no other available HG machine or sometimes invites you to create a homegroup.  It was a nightnare.

  • New Windows Vista user account access

    I'm running a new Dell with Windows Vista Edition Home Premium and have had no problems of access to our wireless internet access. I created a new user account (not asked) the other day, but for some weird reason, I can't access our wireless thanks to the new account.
    The computer recognizes the wireless signal, but there seems to be a connection problem. How can I get the internet to work on the new user account?
    And just in case where, I know absolutely nothing about computers. We are talking about computers for the tips zero here, please.

    Thanks for the quick response, the lot.

    I've followed all the steps and was still scratching my head, but an error message popped up while I was in the new account, saying: there was an adapter error. I have a D - Link USB wireless network card thingamijiggy, so I took and plugged into the computer.
    He then asked me to confirm my password to access the wireless - perfect internet connection account, no worries.

    Bravo again.

  • Unknown user account

    We had problems with our computer, and I was on the phone with Microsoft for 2 hours on 04/06/2013.  She said that if someone had a "password" protect her not access to resolve this type of problem and if I continued to have problems that his supervisor will have to solve the problem.  I saw a user account pop up from time to time and have no idea why or how is added.  The user name was "Unknown account" when I started typing and is now "S-1-5-21-1707336200-2697870300-4147613902-1001" with "special permission".

    When I tried to copy and paste, this is what has been copied.

    \\localhost\C$\@GMT-2013.06.23-11.47.18\Users\Gar-n-Deb

    This all started because even if I was not at home, my husband got a phone call from someone who told him that they were Microsoft and was concerned about the volume of activity, they have seen and could solve the problem, if it was allowed access to the computer and buy software.  He said this looks suspicious and the guy said, I ask only to help you.  Thus, he had access.  The guy had problems with getting their approval on the credit card, but he had already acceded to our computer.  When I got there, I heard my husband say: "well, my wife is home now and I told him look and he hung-up.  We have our phone CASE which is our local supplier and had lost the connection cable, our desktop icons were hidden and I have no idea what else has happened.  Even if one of the owners I have used to work to help me with IT, I'm not at all a computer scientist.  So I called Microsoft and was informed I thought, that Microsoft does not call.

    After my time 2 call with Microsoft, I was monitoring our computer and attempts to change what I thought others prevents access to our computer.  I first noticed that the security of all the icons changed.  I deleted all the icons and then added them back.  After noticing changes more, I then removed remote access.  I don't know how I saw it, but I discovered there where there are 3 home groups.   Now this morning, each file was consulted and specified above user has special permission for everything.

    Maybe I just need to call Microsoft again, but I wanted to at least get this documented.  Please notify.

    When you give full access by a total stranger on your PC your husband fell for a popular scam. The scammer could easily have installed keystroke logging software. If it was my machine then I would perform a destructive factory restore, if it isn't because I have no desire for an outsider to look over my shoulder when I do my stuff from Internet banking or order via the Internet.

  • Extra ' ' my Documets folder in my system and the USER account.

    I use XP Pro and my system has been reinstalled around March. I was bound and not not determine that this happen. I went to Western Digital and watched the external 500 GB drive. They were always out of stock, so I said the * with it and go the 1 Terabyte.The lead first had problems so I had to wait again. When it arrived I started to drag / drop my file on the external drive. Somehow. and I don't know how to explain 'USER', that is Documents and settings - all users by default Administrator USER user the "USER" account earned an extra folder called got an additional file 'My Documents' on this account, it is a system file and I can't remove it. " I CAN move it. So should I just day forget about it or just keep three "My Documents" on my system. Note that the extra "My Documents" file is not on the external drive. I know I asked this before. I tried all the suggestions, but good number of suggestions I could not follow because the procedure was not on my system.

    All user accounts have the 'My Documents' folder and some of them are not the standard user system or administrator accounts that don't care.

    As long as you save in 'My Documents' in your profile then life is simple. Your profile is physically located in C:\documents and setings but do not venture here as your dekstop icons already give you shortcuts to 'My Documents'. Voila

    Take control of the laptop with a password protected administrator account. Create an account for your son. If he cracks then your password, which is very simple with the right software, completely take over the laptop.

    Under updates important area is grayed out and cannot select to change

    Hello Bill,

    Thank you for visiting Microsoft Community.

    As I understood it, you experience the problem, you cannot change the automatic updates even if you are logged on as an administrator user account. The option is grayed out on the system.

    Certainly, I understand your concern.

    I would suggest trying the following steps and check if that helps.

    1. Open the editor of the register of the command RUN by typing "regedit" and click OK.
    2. In the tree on the left, open following files-online HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\WindowsUpdate.
    3. Remove the automatic "Update" folder This will remove all previous settings for automatic update.
    4. Open the automatic update of the control panel and option as usual.
    5. If automatic update is always gray, type the command "gpupdate/force" RUN and click OK or restart the operating system.

    Note: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems can occur if you modify the registry incorrectly. Therefore, make sure that you proceed with caution. For added protection, back up the registry before you edit it. Then you can restore the registry if a problem occurs.

    Hi all

    I was wondering if there was anyway to add and remove users from a Windows Server 2003 using PowerCLI system.  Ideally, I expected to find a way to eventually automate a way to add and cancel the accounts with a script.

    Thanks for any advice that anyone can give or you can push me in the right direction.

    No, I was aking because you can't do a "psexec \\computername.

    The name must be resolved through DNS or WINS, so there should not be any need to move to IP addresses.
