Welcome to LQ.

What specific "strange things" are you seeing, and in in which logs?

Please review this link to learn more about how to post more effective information with your question and enable your fellow members to be able to provide you with some possible, helpful assistance.

The phrase "I have ran anti virus" is a bit telling...what version/distro of Linux are you using?? Or are you using Windows? And what do you mean by "cleared my hard drive"??

I am using windows an i did the hard reset for gard drive an reinstalled windows. I also went as far as replacing my wifi router. Xfinity but 10.10.01 will not go away. I have set up password an username an i am still getting the generic backdoor. I am so frustrated. Any help would be appreciated

As already posted we need specific information. Post what strange things you are seeing in your logs.
I assume this is your laptop. What do you mean by still getting the generic backdoor?
I assume you mean 10.10.0.1 which is typically the default IP address for your router (as I remember...) and will never go away but can be changed. I can't vouch for the overall security of your router but Comcast uses a long random string for the wireless password by default although the username/password for the configuration login is typically the same for all units.

Depending on your account settings and the model number of your router you might have a guest hotspot automatically running i.e xfinitywifi. This is a public open wifi access and separate from your private LAN. You can go into your online account and disable the hotspot feature if desired.

Since you ask here ...

... if you've backed up your data properly, I'd recommend a better approach: Download an LTS version of Ubuntu or Linux Mint and install that instead. Otherwise the holes in the legacy system are just going to be exploited again and again. Neither are perfect, but choosing one to move forward with a necessary step to get out of the current mess.

No, your default route won't go away, since that's how you access the Internet. Every OS will have a default route.

And if you're using Windows, wouldn't you be better off asking your questions on a Microsoft/Windows forum, instead of LinuxQuestions???
