When you protect your computer against viruses and harmful malware you would be surprised at the sheer amount of things that your anti-virus program misses. GlassWire is an additional method of protection that works along with your existing firewall software for added protection. According to their website, their program helps to reveal any extra threats that your original firewall may have missed. When you visit their website you’ll be able to review all of the features that are included with the program and you can download the software entirely through their website. If you have any questions about the program, be sure to visit their online forum or their blog.
