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 definition of computer virus has been given by the Hungarian security researcher Péter Szőr: "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 – 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. I wasn't sure if this was a known issue or if it's just me.See also: Timeline of computer viruses and worms 1949–1980 period (pre-antivirus days) Īlthough the roots of the computer virus date back as early as 1949, when the Hungarian scientist John von Neumann published the "Theory of self-reproducing automata", the first known computer virus appeared in 1971 and was dubbed the " Creeper virus". It turns out that all the other devices are fine, just not my macbook, and I'm noticing it happens about 4 to 5 times a day on average now. This definitely wasn't happening before.Īs I mentioned I initially suspected my router and even went as far as to get a new one from the ISP. It doesn't last very long, maybe 20-30 seconds, then it reconnects and everything is fine. I even ran a wifi speed test on my other mobile devices while my macbook just hangs. I thought it was my router, however, I tested other wifi connected devices during these episodes and they're all fine. Wifi interruptions several times a day on my Macbook pro 2021 (Monterey 12.3.1) So I work remotely, and lately I notice that several times a day my connection hangs, for example, on youtube everything stops and the video wheel circles on the video I'm watching, I try and open a new window to google and nothing, all my work logins just hang.
