A lot of the applications we use nowadays have something to do with the internet in one way or the other. For instance, Dropbox requires constant internet connectivity to sync files between your local Dropbox folder to the one on the cloud, apps like Google Talk need internet connectivity to let you communicate with others, and even tools for offline use need internet access every now and then to update their data. In the most severe cases however, a malicious program sitting in some deep corner of your PC might be silently sending confidential information to someone, without you even knowing. This is where SterJo NetStalker
comes to the rescue. This simple application acts as a firewall between your PC and the internet to keep an eye on all TCP and UDP connection established by currently running services and applications. It’s designed to constantly monitor your network traffic, and lets you block any processes from Internet access by creating rule-based policies.
Antivirus and anti-malware programs are the part and parcel of every PC. Our computers now carry so much information of our credentials and other important data, there is absolutely no room for any kind of security loopholes. However, no matter how many precautions you take, various external threats still make their way in through the internet. If you’re not satisfied with your current antimalware software, then give Roboscan Internet Security
a shot. The developer touts it as a Dual Engine security application, comprising of BitDefender and Roboscan’s Tera Engine, both of which work in conjunction to provide multi-layered protection. Another keystone feature is its Smart Scan Technology that makes the scan process pretty fast and effective, by keeping previous scan records in its Whitelist for future references. A firewall is also incorporated that provides real-time virus protection, and the application comes with an integrated file shredder to get rid of your unwanted data for good. The elegant UI not only looks fascinating, but also provides plethora of options and settings.
Windows Firewall is a vital system security and packet filtering component of Windows. This celestial feature enables users to create inbound and outbound data traffic rules to protect their PCs and network from malicious external sources, such as trojans, viruses, and hack attacks. The major function of Windows Firewall is to restrict third-party applications from sending and receiving data to unauthorized users/apps. Firewall generally automatically identifies trusted sources and adds an exceptions. Likewise, if a software seems fishy, it asks you about manually granting or blocking the permission. However, the Windows Firewall is not utilized up to its full potential by most users because it seems a bit tedious to configure and unleash its prowess. Most casual users cannot get the hang of its inbound and outbound rules. Back in 2008, we brought you a detailed guide on How to Create Exceptions in Windows 7/ Vista Firewall
. Today, we have an application for Windows, which might provide an alternative and easier solution. It is called Firewall App Blocker
, and allows you to add applications to the Windows Firewall block list via simple drag and drop operation. In addition, the application lets you set Windows Firewall policies by providing you with easy access to Windows Firewall with Advanced Security dialog box.

, Proxy + Privacy Browser
is an Android web browser that lets you access all such websites that are either blocked using a firewall, or have been banned in your country altogether. This may include several social networking and media sharing sites, entertainment-oriented sites, blogging platforms, web hosting services or virtually any website that is blocked in either just your premises, or the entire region. Apart from letting you bypass all sorts of proxy barriers, the app maintains your privacy by letting you surf the web anonymously, lets you chose the user agent to browse a device/OS-specific variant of a website, and provides you with several other customizable settings to give you a secure and liberated web browsing experience. The app sports a simple web browser interface with just a minimal set of features; however, it does its job of letting users anonymously browse blocked websites quite effectively. In doing so, the app utilizes several IP addresses as well as proxy servers to bear the amount of load that might be laid on it by worldwide users (many of whom are likely to be students).
In the past, we have featured numerous system repair and performance optimization tools for Mac OS X, including OnyX
, and IceClean
, which enable you to check fatal system exceptions, repair errors and, and perform various system cleanup operations over entire system to boost the overall performance. If you’re looking for an automated system optimization and cleanup tool to check system for Disk, Memory, and Network issues, and apply quick fixes, iBoostUp
is probably just what you need. iBoostUp isn’t meant to replace your existing system optimization utilities, and it can work in conjunction with other tools without showing any issues. It comes packed with a powerful system cleaner to purge system and applications’ left over superfluous data, and browsers’ temp & cookie files.

is an open source firewall for Windows that makes use of the NTKernel drivers. By using fireBwall, you can manage all of your TCP and UDP connections. All that is required is to configure your network adapter and to choose which ports will be whitelisted. By default, fireBwall blocks all incoming new connections, therefore, you will have to manually configure all incoming and outgoing connections after fireBwall installation. With performing these basic configurations, you will not be able to use the internet and will also encounter access issues on your local network.
Using the Firewall can help secure a system by blocking unwanted (and potentially malicious) incoming connections. Many users turn off the default Windows firewall due to the number of annoying pop-ups and confusion in configuration that they have to deal with. This is particularly true for the Advanced Firewall in Windows Vista and Windows 7. TinyWall
is an easy to use tool that makes it possible for common users to use Windows firewall, without having to deal with any annoying pop-ups, and provides users with the option to whitelist or unblock programs easily. For example, you can initiate connection white listing using a hotkey, select an application from the list of running processes, and allows completely enabling/disabling all connections in a click.
Like Windows, where malicious applications can gain access to network over TCP/UDP protocols, Mac OS X is also prone to such attacks not only from internal programs, but also from external scripts and apps that connect with system through internet. Although Mac OS X’s native Firewall app tries to block all connection requests from external sources, it doesn’t keep a check on internal applications that send requests to connect with internet, or try to communicate over TCP or UDP ports. Whether you haven't installed a staunch security application or Mac OS X native Firewall settings are too lax, you need an application like TCPBlock
. It secures Mac from those installed applications, processes and scripts, which either attempt to surreptitiously communicate with external sources over TCP or UDP ports, or open connections to networks without asking for permission.
Windows Firewall is a software firewall and packet filtering component of Windows which helps users create inbound and outbound rules to protect their network from being compromised. Like all firewalls, it protects the networks from unauthorized access while allowing legitimate communication to pass through and by blocking malicious, specified or user profiling agents. Unfortunately, the firewall settings can be a bit difficult for many home users to configure. For this reason many users prefer keeping their Windows Firewall Off for avoiding network disruptions. Windows Firewall Notifier
is a portable application which makes it easy to configure firewall rules (both inbound and outbound) by providing prompts similar to UAC (User Account Control) for allowing and blocking network traffic.
