It protects your system from viruses, Trojans, worms, hacker attacks, and other threats. Take Comodo Firewall: This full-featured, multilayer firewall application uses cloud-based data to analyze new programs and data to prevent attacks, including zero-day attacks. It does a good job, but there's no reason not to take advantage of much more capable (yet just as free) firewalls, especially when they're easier to use and come with significant extras. A patch that fixes the problem is already available here.If you're running a fairly recent edition of Windows, you're probably also using the built-in Windows Firewall.

In most of the cases, PrivDog comes bundled with several Comodo products, such as Internet Security, Chromodo, Dragon and IceDragon (the last three are browsers), but all these applications use a different version of PrivDog which doesn't have this vulnerability.Īccording to an official statement from the company, this 'potential issue' only exists in versions 3.0.96.0 and 3.0.97.0 of PrivDog, versions which have never been distributed by Comodo. There is one more detail that makes things even more interesting. Basically, this vulnerability made you a sure target for any kind of man-in-the-middle attack. To put things in simpler terms, if a hacker would intercept the data that travels from your computer to any website (let's say a bank), and then send you back data that originated from his computer, PrivDog will accept it without even realizing that it's coming from an outside source and not the bank that you were trying to connect to. As far as I know, even the most basic browser wouldn't make such a huge security error.

However, the developers of the application made one small oversight: PrivDog doesn't correctly verify the security certificates that it receives from the websites. According to its promo, this way everybody wins: consumers, publishers and advertisers alike.

Basically, what the tool does is it takes the potentially threatening ads and replaces them with secure ones. The app is designed to you keep safe from malicious advertisements while you're browsing the web. PrivDog is a Web security application with strong ties to Comodo. Comodo is a big international company which, among other products, also develops Comodo Firewall and Comodo Internet Security.
