Wow thanks. That cleared the issue up really well.
I found out that I was infected by Github through clicking a link to a recipe using meat. Apparently Github targets meat eaters and people who visit animal based recipe sites and shops. So I highly recommend all meat eaters to take this step to protect themselves as well.
Github isn't maleware. Having Github can leave you open to malware because it chooses which projects you leave open to the internet - people have exploited that.
If you think you got Github by visiting a site that has regular meat recipes, you're either sadly mistaken or being tricked by a vegan.
