Is it possible to install antivirus software on a router and can it become infected with viruses?
Are you worried about someone hacking into your Wi-Fi network without your permission? Or that they could be spying on you from a connected device? Sometimes we think that having a good antivirus program on our computer is enough. But if your router isn't properly protected, your entire network is at risk. Today, I'll tell you why this is a problem and what you can do to avoid it, with easy-to-implement tips.
Routers are considered the first line of defense against all internet threats. Cybercriminals often target these devices to gain access to the entire local network. For this reason, some brands, such as ASUS, TP-Link, and NETGEAR, have integrated antivirus software and various security measures, such as Intrusion Prevention Systems (IPS), into their routers to add an extra layer of security.
Do I need antivirus software on my router?
The short answer is no, you cannot install antivirus software on your router. These devices run on firmware (a more basic type of software) and are not designed to run antivirus programs like you would on a computer. However, this does not mean they cannot be a target for hackers. A misconfigured router can act as a gateway for all your connected devices.
Can routers get viruses? It's very rare, but yes, it is possible for a router to be compromised. This isn't usually because it stores data, but because it controls the traffic flowing into and out of the network. If an attacker manages to tamper with your router's firmware or DNS settings, they could redirect you to fake websites or intercept your communications. One notorious example was the 2017 attack on thousands of routers, which prompted the FBI to recommend that everyone restart their routers and update their firmware.
- 12 essential tips for protecting your router and local network:
Securing your network isn't just about having a good password. Your router is the gateway to all the connected devices in your home: your phone, laptop, cameras, smart speakers—everything goes through it. If someone manages to hack in, they can see and control far more than you can imagine. That's why we've put together this list of 12 essential tips to secure your router starting today, even if you're not a tech expert.
- Update your router's firmware: Updates fix security vulnerabilities. Enable automatic updates if your router allows them, or check the manufacturer's website every few months for a new version.
- Change your router password: Many routers come with default passwords that anyone can find online. Set a strong and unique password to access your router settings.
- Change the network name (SSID): Avoid using your last name or anything easily guessed. Use a generic name that doesn't give any indication of what type of router you're using or who lives in the house.
- Activate WPA3 or WPA2 encryption: This keeps your Wi-Fi network secure. If your router is new, activate WPA3. If not, at least make sure you're using WPA2-AES.
Disable features you don't use, for example, remote administration or UPnP, which are usually enabled by default. If you don't know their purpose, it's best to disable them.
- Create a guest Wi-Fi network: If someone comes to your home, do not give them the password to your main network. Create a separate network for guests or less secure devices.
- Set up a good firewall: Many Razer devices include a firewall, but it is sometimes disabled. Go to the settings and make sure the firewall is turned on.
- Restrict external access: Close unused ports and disable features like access from outside the network. The less visible your network is to the outside world, the better.
- Enable two-factor authentication (if available): Some modern routers allow you to use an additional app or code when logging into settings. This is an extra layer of security that is highly recommended.
- Don't use easy or repetitive passwords: Avoid words like "123456" or "password." Use long passwords that include numbers, letters, and symbols. If you have trouble remembering them, use a password manager.
- Monitor connected devices: Log in to your router's dashboard periodically and check which devices are connected. If you see a password you don't recognize, change your password immediately.
- Consider upgrading your router if it is too old: If your router has not been updated in years or does not support WPA2 or WPA3, it is time to upgrade to a more modern and secure device.
You don't need to be an expert to improve your network security. With these tips, you can close many of the doors that cybercriminals often exploit. Your router is the guardian of your connection. Take care of it, update it, and protect it well, and the rest of your devices will be more secure too.
