What are the threats?
There are over a billion people using Internet on daily basis. We are doing this from home and from our workplace;
from our personal computers, laptops, mobile phones and TV sets; to search for information, to communicate with
other people and to buy and sell goods and products. There is more - just think about the personal information that is stored
on your computer - your e-mail messages, your personal photos and videos, chat logs, browser history, history of the all
recent documents that you have read or created.
What happens if all this information falls in the wrong hands? Disaster. But how this could happen? The information is on your
computer and you never send your personal information over the Internet. The dark truth is that there are countless ways for
people with malicious intentions to invade your privacy. All they have to do is to place a small program (malware, trojan or virus) on your
computer. The malware than will search for valuable information and will send it to its creators. After that they will most probably use your
computer as a tool to infect other computers, to attack Internet sites for profit and to send spam messages.
How to protect your information? The best strategy is to create a multi-layer defense around your computer. The first important step is to remove
and shred all private information that is not useful anymore but still can be dangerous if stolen. You can do this with the powerful privacy
protection tool Mil Shield that will automatically clean all online and offline traces from your computer.

In order to understand the other precautions you can take, lets see which are the most common ways to steal information and
get control over your computer:
- Infecting of the computer through download of malicious program. One of the great advantages of the computers is
the vast variety of programs that can be downloaded and installed. Most of these programs are genuine and can be trusted but more and more
viruses, trojans and rootkits disguise themselves as useful programs. One special case are the modified versions of respected programs that are
infected with malware and adware or the so called cracks for popular programs.
- Infecting through files that are not looking like programs at first glance. For example you may download a song or
a video file from the Internet and it may contain an executable file. Another common example are the screensavers, which are
programs and are just as dangerous as any other program.
- Using security "holes" in the operating system or popular applications. The so called exploits use the security
problems or "holes" that are unintentionally left open in every major operating system and many popular applications. While most software companies
are releasing security updates relatively quickly, most users never upgrade their software or it is too late - they are already infected and
closing of the security "hole" does not remove the malware that is already on your computer.
In the first two cases above, you can prevent the infection if you are careful not to download programs from suspicious sources (always prefer
downloading from the site of the author of the software or at least make sure that the download link points to its site). However, it the third case,
you can not do anything to stop infection because there is no need to download and install anything - sometimes just a browsing of an infected Web
page is enough to get you infected with malware.
The dedicated antivirus and anti-spyware programs help but they suffer from the same problem as the security updates - when the malware
is included in their virus definition updates, it is already too late for the vast majority of infected PCs. Furthermore, they degrade the speed
and usability of your computer (sometimes to a crawl) because the constant scanning of all files and processes is very demanding task.
Here comes the essential role of the firewall in the multi-layer defense of your computer. The firewall serves as a guardian, who monitors
everything that your computer sends to or receives from the Internet (or the local network, if your computer is connected with other PCs from your house
or your company). Mil Firewall is an easy-to-use personal firewall program, which makes sure that you are in full control of what goes in or goes
out of your computer.
