Making programs using a freeware tool has some drawbacks... McAfee or NOD detect DrawAid or any other program written in AutoIt as "malicious". They're actually false positives; the AV companies don't really care about freeware tools. At least Softpedia guarantees that DrawAid and Universal Screenmate are 100% CLEAN, making them a more reliable source.
