You need a license in order to make your own antivirus. Creating an antivirus without license is illegal. My guess is that to create an antivirus, you need to be good in coding, designing your antivirus'interface and needs a lot of Malware database (around 10000-20000 databases( or more) is required) in order for your antivirus to work. A special program is also needed to make an antivirus program.
I strongly advise you not to create your own antivirus. This is just my guess, take it with a pinch of salt because creating your antivirus is extremely complicated.
