I love this project because not only do I like the effort the developer puts into it (think about how many hours he has spent developing this software, answering all the questions here, contacting VirusTotal for inquiries on usage to make sure he's staying within the boundaries, etc)... Countless hours over the YEARS.
As well as this, I have never seen the developer lie about his project... He doesn't claim it will detect "99.9% malware" or that it's more powerful than other products and he doesn't make promises he can't keep... I just see a recursive pattern of lots of hard work to implement new features and keep things well-maintained.
Even when he had to take that long break (last year?) he returned and instantly hopped back onto the Crystal Security development.
Honestly I love this project and I have mad respect for the developer. Usually I am not a fan of ".NET security products" but this one is a definitive exclusion to that; I'm even going to use it myself
