Any links to xojo built antivirus or better still,can one use xojo to build antivirus App.? Just want to know.
I don’t think I’ve ever seen one written in Xojo, but it should be doable as all you are doing is opening files and checking against a database of known signatures (have fun building that database 
) If you want to get more advanced features in your program, it’ll take more time and learning… Good luck 
Yes, I’ve created one long time ago. However, for better performance when scanning, don’t iterate with FolderItem.Item.
