ISSUE: Whenever I type "i" in lower case it changes the search to iron-start, it doesn't do it with a capital "I". Is this something built into chrome or malware? I have reinstalled Chrome, and reinstalled my OS for other reasons, but once in a while I notice that this still shows up. What is it? How can I remove it? I looked at the website and it doesn't look right. I checked all the extensions as well and don't see anything, and reset chrome to its original settings.
Solution: After further investigating, this turned out not to be malware or a browser hijack. In settings of Chrome, under Search, I clicked "Manage Search Engines". In here iron-start.com was listed as a default search engine with the keyword short cut "i". I simply removed this and it no longer pops up in the URL bar when typing "i"
Reason: A Couple years ago I installed a program called SRWare Iron, an alternative to chrome, and I believe in doing this, it insert this search engine into my chrome browser. I knew my computer was not infected due to me wiping my computer a couple times due to other reason, as well as reinstalling chrome and reset to default settings. What I found out was that the issue persisted at work and home, where I was both logged into my gmail. It was clear that the default search engines were synchronizing from my gmail account.
