Why are Blank and Secure free to download? I have no idea because after doing a search for "blank and secure" on Google, I came up with only one site that actually had the application (it was free but you had to pay for the upgrade). The main reason why the software is free to download is because it's an open source project. This means that anyone who owns the source code can write a lot of modifications to it and make it compatible with their programs such as PCs and Smart Phones. If you own the software and want to give it away to your friends, family or other people you can do that as well. But to be honest, I can't see any big reason why you would need to give the software away.
The biggest reason why Blank and Secure should be free to download would be because it's the best anti virus and spyware software available for free. When I downloaded the program, it installed very quickly and without any hassle. It's very effective at removing malicious software from my computer, so I decided to give it a try. It installed and loaded up faster than my previous software which gave me a lot more time to relax and enjoy my free software.
As you can probably tell by now, I am a huge fan of Blank and Secure. I don't use any other program other than this one for my personal use. In order to keep my computer clean, all I do is run a scan on a weekly basis with this application and remove viruses and spyware that are hidden deep inside my computer. The free download will always be my first choice for downloading programs because it comes highly recommended by friends and family. You can also scan your computer with it at times to ensure that it doesn't come back after a software install.
