Usually, in HN, don't make a small comment about your own submission. Reply to the questions in the threads, but try not to write a new comment. (Sometime it's a good idea to make a comment.)
Both projects you have submitted look like things that a good antivirus should detect and block. Do you have a project that is less controversial?
You submitted two projects in one day. If your plan was to continue submitting two projects each day, then I think it's too much. If your plan was to submit only one project per week, then I think it's ok.
I prefer an blog post about some interesting detail or technical problem of you project than a direct link to github. Both projects have a good readme.md, but a long blog post is usually better to get attention here. (But not too ling.)
