Hi. I was browsing the net yesterday on my phone (looking at info about a pain killer I'm taking), when a message saying 'Installation complete' popped up. I wasn't downloading anything at the time, so it got me a bit worried. I was using Firefox at the time with free lookout running, but spotted last night that I had the 'enable app installs from non play store' ticked. I have since uninstalled Firefox, and ran scans with AVG and Avast, both of which didn't find anything. Any ideas about what it could have been, or a better way to check for issues? Cheers.
