Hi, Will be a pleasure to work for you on this. I am a kernel developer, maybe the only fully specialized in that kind of works (because I don't work in anything else ;-) ). I already have worked several times for antivirus companies. I see you have very clear what features you want in your product. I have to mention that is not a trivial task, but for someone with experience like me is like the half of the way ;-)
You already have an engine to scan the files??? I could use some open source engines?? I have to develop my own?? (You know the real time protection consist in a filter driver, a service in user mode and the engine libraries to scan the files and send the results backward)
Please ask me any details, will be a pleasure to reply.
Please take 2 minutes to check my work history and you will be surprised how much I gather all your requirements.
Thanks in advance, SysSoftw
