My PC attacted by sniff/spy/hack

[rocky]

Hello,

 

I Found that my windows 10 version mostly is the one that is attacked by a hacker that sniffs in my PC in order to watch/spy and maybe doing more things that are NOT wanted.

My Pc can be infected and things might change. I also have a windows 7 version and think that one also got attacked but not so much/hard as windows 10 version.

 

Is there a way to LIMIT a hacker to my PC while I am on internet (wireless)???

I use Mac Affee antivirus/firewall

I am thinking of installing

a) anti malaware

b) spybot

 

Is there OTHER program /ideas that be helpfull to avoid a hacker get access to my PC or restrict his right while I am on internet???

Is a hide my IP program usefull in such cases or something else?

Is someone sniffing and eavesdropping on your Wi-Fi traffic, stealing your passwords and credit card numbers?

So what do you do? Follow these tips and you'll be well ahead of most home Wi-Fi users. Nothing will make you 100 percent safe against a truly dedicated hack. But don't make it easy on them; protect yourself with these steps.

Tips to secure your router Wi-Fi network.

Change Your Router Admin Username and Password
Every router comes with a generic username. You need it the first time you access the router. After that, change them both. Immediately. The generic usernames are a matter of public record for just about every router in existence; not changing them makes it incredibly easy for someone who gets physical access to your router to mess with the settings. So aywiresufzklthfrs is an okay password, ayw4r2s8f8kl43f2s is even better, and a!w4_2s8#8kl43f2% is the best. 

If you forget the new username/password, you should probably stick to pencil and paper, but you can reset a router to its factory settings to get in with the original admin generic info.

Change the Network Name
The service set identifier (SSID) is the name that's broadcast from your Wi-Fi to the outside world so people can find the network. While you probably want to make the SSID public, using the generic network name/SSID generally gives it away. For example, routers from Linksys usually say "Linksys" in the name; some list the maker and model number ("NetgearR6700"). 

That makes it easier for others to ID your router type. Give your network a more personalized moniker.It's annoying, but rotating the SSID(s) on the network means that even if someone had previous access—like a noisy neighbor—you can boot them off with regular changes.

Activate Encryption
This is the ultimate Wi-Fi no-brainer; no router in the last 10 years has come without encryption. It's the single most important thing you must do to lock down your wireless network. Navigate to your router's settings and look for security options. 

Each router brand will likely differ; if you're stumped, head to your router maker's support site. Once there, turn on WPA2 Personal (it may show as WPA2-PSK); if that's not an option use WPA Personal (but if you can't get WPA2, be smart: go get a modern router). Set the encryption type to AES (avoid TKIP if that's an option). You'll need to enter a password, also known as a network key, for the encrypted Wi-Fi.

Turn Off Guest Networks
It's nice and convenient to provide guests with a network that doesn't have an encryption password, but what if you can't trust them? Or the neighbors? Or the people parked out front? If they're close enough to be on your Wi-Fi, they should be close enough to you that you'd give them the password.

Update Router Firmware
Just like with your operating system and browsers and other software, people find security holes in routers all the time to exploit. When the router manufacturers know about these exploits, they plug the holes by issuing new software for the router, called firmware. Go into your router settings every month or so and do a quick check to see if you need an update, then run their upgrade. New firmware may also come with new features for the router.

Turn Off WPS
Wi-Fi Protected Setup, or WPS, is the function by which devices can be easily paired with the router even when encryption is turned on, because you push a button on the router and the device in question. Voila, they're talking. It's not that hard to crack, however, and means anyone with quick physical access to your router can instantly pair their equipment with it. Unless your router is locked away tight, this is a potential opening to the network you may not have considered.

Disable DHCP
The Dynamic Host Control Protocol (DHCP) server in your router is what IP addresses are assigned to each device on the network. For example, if the router has an IP of 192.168.0.1, your router may have a DCHP range of 192.168.0.100 to 192.168.0.125—that's 26 possible IP addresses it would allow on the network. You can limit the range so (in theory) the DHCP wouldn't allow more than a certain number of devices—but with everything from appliances to watches using Wi-Fi, that's hard to justify.

For security you could also just disable DHCP entirely. That means you have to go into each device—even the appliances and watches—and assign it an IP address that fits with your router. (And all this on top of just signing into the encrypted Wi-Fi as it is.) If that sounds daunting, it can be for the layman. Again, keep in mind, anyone one with the right Wi-Fi hacking tools and a good guess on your router's IP address range can probably get on the network even if you do disable the DHCP server.

Filter on MAC Addresses

Every single device that connects to a network has a media access control (MAC) address that serves as a unique ID. Some with multiple network options—say 2.4GHz Wi-Fi, and 5GHz Wi-Fi, and Ethernet—will have a MAC address for each type. You can go into your router settings and physically type in the MAC address of only the devices you want to allow on the network. 

You can also find the "Access Control" section of your router to see a list of devices already connected, then select only those you want to allow or block. If you see items without a name, check its listed MAC addresses against your known products—MAC addresses are typically printed right on the device. Anything that doesn't match up may be an interloper. Or it might just be something you forgot about—there is a lot of Wi-Fi out there.
