WebOne way to protect against viruses, therefore, is to create a hash value for a program when it’s distributed to users (i.e. run the computer code through a hashing algorithm and get a hash). Then, whenever that program is run, create a new hash value for the file you’re about to run. Compare the new hash to the original hash.
