Themida has been developed to thwart the process of reverse engineering adopted by unscrupulous computer geeks to know the knowhow of how certain applications work. It is a software protector for use of the software developers designed for protecting their creation against software cracking. However, it is somewhat different from other software protectors which themselves are often cracked by software crackers.
What Themida does is use the SecureEngine protection technology for securing itself as well as the software being developed. When you run the utility in the highest level of priority, it enforces advanced protection techniques so that software crackers can neither crack it nor the application under development.
