Hahaha don't worry dude it happens to the best of us. I almost got caught out installing a mod I stupidly downloaded of a site I wasn't exactly up on when I caught it trying to ask for permission to install mysearchbar or one of the other web search redirects.
I can't belive people still download trial software from cnet. Literally every package there has some form of malware. I don't even bother with java on Windows much these days since Oracle took over.
AHAH oh god Java! I'm struggling to resist not installing it, even tho sooner or later I'm gonna fall for it as one of the programs I use to work needs it to do some useful stuff.
