How to get Torch browser to stop prompting me to update to new version?
Scroll down on this site (http://www.shouldiremoveit.com/Torch-5557-program.aspx) and you'll see something that's known to come with Torch called torchhelper.dll. 

I dug into Activity Monitor to gather data about Chrome (I really don't want to download Torch) and found all this when expanding the Chrome app section (while using Chrome to bring it up to the top):


So try this and tell me what happens: open up Activity Monitor on your Mac, go to the Memory tab, then search (top-right) for Torch. Take a screenshot of what comes up! Try killing the processes (tap on whatever helpers come up and press the X in the top left) and see what happens).
