Possibly, the first publicly documented removal of an 'in the wild' computer virus (i.e. There are competing claims for the innovator of the first antivirus product. However, as internet usage became common, viruses began to spread online. During this time, virus checkers essentially had to check executable files and the boot sectors of floppy disks and hard disks.

Antivirus software came into use, but was updated relatively infrequently. Д«efore internet connectivity was widespread, computer viruses were typically spread by infected floppy disks.

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. 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. From then, the number of viruses has grown exponentially.

The first IBM PC compatible 'in the wild' computer virus, and one of the first real widespread infections, was ' Brain' in 1986.

Cohen used the term 'computer virus' to describe programs that: 'affect other computer programs by modifying them in such a way as to include a (possibly evolved) copy of itself.' (note that a more recent, and precise, definition of computer virus has been given by the Hungarian security researcher PГ©ter SzЕ‘r: 'a code that recursively replicates a possibly evolved copy of itself'). In 1983, the term 'computer virus' was coined by Fred Cohen in one of the first ever published academic papers on computer viruses. The first known that appeared 'in the wild' was ' Elk Cloner', in 1981, which infected Apple II computers. The Creeper virus was followed by several other viruses. Some people consider 'The Reaper' the first antivirus software ever written вЂ“ it may be the case, but it is important to note that the Reaper was actually a virus itself specifically designed to remove the Creeper virus. The Creeper virus was eventually deleted by a program created by Ray Tomlinson and known as ' The Reaper'. This computer virus infected Digital Equipment Corporation's ( DEC) PDP-10 mainframe computers running the TENEX operating system.

Some products also include protection from other computer threats, such as infected and malicious URLs, spam, scam and phishing attacks, online identity (privacy), online banking attacks, social engineering techniques, advanced persistent threat (APT), and botnet DDoS attacks. In particular, modern antivirus software can protect users from malicious browser helper objects (BHOs), browser hijackers, ransomware, keyloggers, backdoors, rootkits, trojan horses, worms, malicious LSPs, dialers, fraud tools, adware, and spyware. However, with the proliferation of other malware, antivirus software started to protect from other computer threats.
