Recently I noticed I have a 2.1.2.3 application and I have no idea what is it or how it got on my system, further to this when I start up my PC I get a random Mozilla Firefox popup labelled random characters that I can't maximize and just disappears. I'm pretty sure I never installed firefox. I'm not sure if this is dangerous or not but its unwanted and sounds similar to these posts when I was looking it up;

I haven't uninstalled anything yet as firefox doesn't appear in my uninstall menu, would appreciate any help, thanks guys!
