1. Unknown Computer On My Network Windows 10

Hi everyone,While transferring files today, I noticed a computer calling itself 'Nikkie' in my network. I did not allow this computer in. We have a wired/wireless Linksys router hooked up by wire to the desktop (the laptops in the house use wireless).

As far as I know (my husband, the former programmer, set up the network, but is deployed so I manage it at the moment) the only security level is that you have to enter the MAC ID of each allowed computer on the router's web page to get access. We haven't ever needed a firewall beyond the hardware version the router supplies, so it has fallen down the list of priorities.My question is: is this someone trying to hack my internet connection and steal my bandwidth, or a virus/worm/etc.

Found Unknown Computers In My Network Places - posted in Windows XP Home and Professional: Did a quick search but could not find an answer. Earlier this week, my wife found four unknown.

Of some kind. If it's an neighborhood interloper, what do you recommend for getting rid of him/her (firewall programs?), etc. Any advice is welcome.Jennifer. It's not only a security issue (and I don't mean to minimize that), but it is also a legal issue.

Providing Internet access beyond your home may be viewed as 'theft of service' by your ISP. I know that the cable companies (such as my local Time Warner) are very sensitive to this issue and see it as a significant potential loss of revenue.So you definitely want to get Nikkie out.

But putting on password security in your router should solve the problem, unless Nikkie is a REAL hacker, in which case you might have a major pain.Bob.

The other day, I noticed two unknown computers and a few Media Devices associated with those computers were on my network. Of course I immediately logged into my router, changed the network SSID and security key, and even blocked the MAC addresses of the Media Devices (I couldn't find the MAC addresses for the computers). That seemed to solve the problem.However, this morning I noticed that the computers and Media Devices are back. And what's really confusing is that they seem to follow me regardless of the network I'm on (I'm on my work network across town, and they're still connected.) This makes me think that it's something on my machine, and not on the network. I scanned for malware, and deleted everything that I found, but that didn't get rid of the machines.Any ideas on what they could be? I have a couple virtual machines on my machine, but I have VirtualBox and VMWare turned off, so I'm pretty sure it can't be those (not to mention the names aren't the same). I'm running Windows 7 Home Premium, if it helps.

I've attached a screenshot of my Network screen. I have only one user account on my computer, Josh. There is a computer and a media device for that user account.

When I'm at home, my router will also show up, as will my Xbox, but I can tell what those are.The computers I'm concerned about are CATMAN-PC (and the associated media device) and IVORY (and the associated media devices). For some reason, the IVORY pc isn't showing up currently, but the media devices are.

Every once in a while one of the two computers will disappear, but the media devices stay connected. The computer will eventually reappear. (I'm not worried about LAURIEMAC-PC, that's a coworker's machine.)EDIT: Now the IVORY machine has showed up as well. It's just another computer on the network, like CATMAN-PC. I can upload another screenshot if it helps.
