The names for the most common types of Internet invaders are always changing, but the goals are the same-someone or something is trying to access your computer to use it in a way you normally wouldn't allow. Fortunately, with a little know-how and the right tools you can stop most threats in their tracks.
Is your device's performance slowing down? Do you wonder why your home page keeps changing or where those pop-ups come from? You can prevent those annoyances and threats with proper prevention, tools and monitoring.
Outdated software and operating systems (OS) are vulnerable to attacks. Ensure your software and OS are up-to-date. Outdated Java and Adobe Flash versions are particularly susceptible to malware infections.

In addition to what you can do to prevent threats, which includes the free Norton Security Suite, and as an ongoing initiative to make the internet safer for its customers, Constant Guard offers tools to detect and remediate against bots, and verify the authenticity of websites accessed.
As an added service of Constant Guard, we may notify you if we believe a device in your home may be infected with a bot. The notification will advise you to follow the steps outlined here to remove the bot from your device and prevent future attacks. Click here to run our instant bot detection test.
DNSSEC (Domain Name System Security Extensions) allows websites and Internet Service Providers (ISPs) to validate domain names to ensure they haven't been tampered with, compromising your online security.
DNSSEC is part of Constant Guard, which helps provide you with the best and safest online experience possible. With DNSSEC, a website name such as www.comcast.net is signed into the Domain Name System (DNS). Then, when you try to connect to that website, the Comcast DNS servers verify its security signature. You will only be connected if the website passes the verification process, which happens so quickly you shouldn't even notice that it's being done. If validation fails on a website, you'll receive a "page not found" or "server not found" error. This process prevents hackers from re-directing you to fake, phishing, or criminal sites.
A bot is a malicious form of software that could use your computer to send spam, host a phishing site or steal your identity by monitoring your keystrokes. As a new feature of Constant Guard, we may notify you if we believe a computer behind your cable modem may be infected with a bot. The notification will advise you to follow the recommended steps to remove the bot from your computer. Follow these steps below to remove malicious software from your computers and protect your identity.
