pop up saying that a device is connected to my Imac with IP

My iMac is completely compromised after having an intrusion on my internet router.

I supported everthing this summer.  I tried to reset my IMac to factory settings.

A pop up came in September saying that another device is connected to my internet

connection with an IP address.  I called my provider of intellectual property, and they said it was a

Xerox printer.  I don't have a Xerox printer.

I followed all the steps in trying to get rid of malware and successfully, I think, to get rid of

It is for 1 or 2 days.  But something else is in my system.

Because I tried to protect my computer.  I'm changing my internet provider

This week and I would like to hide my IP to my iMac.

Hide my IP to my iMac when I'm on the internet?

Depending on your router model, there should be a way of

disable DHCP.  It is a method used by the router to assign

IP addresses on your local network when any device attempts

connect you to it.  You can then manually assign IP addresses to only

These devices that you want to have access to your router.

If you haven't already done so, you must also change the password (and also

username if the router required) to something else and much stronger.

If it is always the default, with which it was delivered, anyone can understand this.

In addition, if the router is a network capable wireless as well, you must disable the comments

access and create stronger passwords.

Also, make sure that all firewalls is enabled on devices and the

router.

As every router is different, you will need to check the manufacturer's instructions

to make these changes.

    Original title: why

    Why my computer says that I am not connected to the internet when I am and no web pages don't show because they say that I'm not connected

    You have McAfee? McAfee has been updated at the same time as the last batch of updates from Windows 7 and this is the cause of problems of internet connection for most, if not all, users of McAfee.

    See the communication from this "criticism" - McAfee

    Some customers may experience a loss of network connectivity and/or errors in McAfee Security Center after a recent update

    You should make the fix McAfee, if necessary. There are corresponding communications for their enterprise products.

  • Windows 8 pro applications say that they are not connected to the internet

    I just installed Windows 8 pro and after installing, everything worked well. However, now all applications say that they are not connected to the internet.

    Shop Windows says "you're PC is not connected to the internet," However, when I go to the Office the internet works fine.
    How can I fix?
    I tried to make a new account and check my internet options, but nothing seems to work.

    After much more research online, I was able to find the problem for my computer. Before moving to windows 8, I had AVG internet security on windows 7, and apparently that's what was blocking the applications to connect to the internet.

    So if you have some type of antivirus or internet security installed, try to remove them to see if that makes a difference.
