You probably know that you need a firewall program to use the Internet safely. In addition to protecting you against attacks from the Internet, a good firewall will also tell you when programs installed on your computer are attempting to phone home and enable you to prevent them from doing it. This is something that Windows’ own firewall doesn't do, and it's essential for identifying and stopping the activities of many malicious virus and spyware programs. For example, this enables you to prevent your computer from being turned into a "zombie" controlled by spammers or destructive hackers.

If you don't have a degree in computer science, using a firewall program can be quite frustrating. In addition to all the confusing jargon, current firewalls are getting to be very big programs. Sometimes you have the feeling that you're installing an entire office suite instead of a basic network tool.

The brand-new Ashampoo FireWall is different. Its Configuration Assistant guides you through every step of the simple setup process. And Easy Mode makes using it a breeze - you don't need any special technical knowledge and everything is explained clearly.

Ashampoo FireWall is also amazingly compact. Even with its four additional security tools it's a tiny program that uses very little memory and computer resources. You get the heavy-duty protection without heavyweight overload on your system.
