The first product with a heuristic engine resembling modern ones was f-prot in 1991. 34 Early heuristic engines were based on dividing the binary in different sections: data section, code section (in a legitimate binary, it usually starts always from the same location). Indeed, the initial viruses re-organized the layout of the sections, or overrode the initial portion of section in order to jump to the very end of the file where malicious code was located—only going back to resume execution of the original code. This was a very specific pattern, not used at the time by any legitimate software, which represented an elegant heuristic to catch suspicious code. Other kinds of more advanced heuristics were later added, such as suspicious section names, incorrect header size, regular expressions, and partial pattern in-memory matching. In 1988, the growth of antivirus companies continued. In Germany, tjark auerbach founded avira ( hbedv at the time) and released the first version of AntiVir (named "luke filewalker" at the time).

modifying them in such a way as to include a (possibly evolved) copy of itself." 14 (note that a more recent, and precise, definition of computer virus has. From then, the number of viruses has grown exponentially. 17 18 Most of the computer viruses written in the early and mid-1980s were limited to self-reproduction and had no specific damage routine built into the code. That changed when more and more programmers became acquainted with computer virus programming and created viruses that manipulated or even destroyed data on infected computers. Citation needed before internet connectivity was widespread, computer viruses were typically spread by infected floppy disks. Antivirus software came into use, but was updated relatively infrequently. During this time, virus checkers essentially had to check executable files and the boot sectors of floppy disks and hard disks. However, as internet usage became common, viruses began to spread online. Period (early days) edit There are competing claims for the innovator of the first antivirus product.
