:I'm not so sure whether this really is a standard Venn diagram. According to quite some sources ([1] https://en.wikipedia.org/wiki/Venn_diagram, section "Overview"; as well as these papers: [2] [http://arxiv.org/abs/1207.6452 arXiv:1207.6452], [3] [http://arxiv.org/abs/math/0603068 arXiv:math/0603068], have a look at p. 1 and pp. 1/2 respectively, also: [4] [http://arxiv.org/abs/cs/0512001 arXiv:cs/0512001], Wolfram MathWold agrees: [5] http://mathworld.wolfram.com/VennDiagram.html), a Venn diagram is "[...] a set of n [– in this case 2 – ...] closed curves [– circles –] that subdivide the plane into 2^n connected regions [...]." [3, p. 1]. So we would actually expect to see 4 regions – in a standard Venn diagram. Obviously here the intersection is supposed to be empty (yielding only three regions), making this effectively an Euler diagram, in which circles are allowed to be the same size -- why should they not (https://en.wikipedia.org/wiki/File:Hamilton_1881_example.jpg). Additionally, Euler diagrams are not only used to illustrate "(for all x) if A, then B" or "all A are B", but also "no A are B" etc. You might also want to have a look at this blogpost concerning Euler vs. Venn: [http://blog.stevemould.com/venn-vs-euler-diagrams/ Venn Vs Euler: The Diagrams]. As this comic is titled "Virus Venn Diagram" one expects to see a classical Venn diagram, one does, however, not get to see one, but rather an Euler diagram showing very drastically that there is no intersection of the set of problems that make one think there might be a virus causing it and the set of problems actually caused by a virus. That's my amount of unnecessary pedantry for today. [[Special:Contributions/89.182.242.115|89.182.242.115]] 12:19, 3 March 2013 (UTC)

Haha, how often do I have this conversation with my parents! They: "I think we are being hacked." Me: "?!" They: "Yeah, this morning when I started my computer, X wasn't working and now Y is acting all weird." ... Yes, of course. --[[Special:Contributions/83.84.33.170|83.84.33.170]] 08:49, 2 March 2013 (UTC)
