Review by Dutch: I use this program on a daily basis for over a year. working in a public library I download 100s of programs to try out first on my computer before installing them elsewhere. this programs has completely protected me from some otherwise very nasty spyware adn viruses. All it took was a reboot and things were back as they were a month ago. Also a 'Deepfreeze' user, a similar program to shadowsurfer, I have had the blue screen of death appear with the last message before dying was from deepfrz.sys - shadow surfer has never given me any problems. infact it has saved my PCs, and my time.

Review by John: Great application. I purchased the m2-s1 scanner and the entire thing is awesome. (5/5 - 11-Jan-2007)
