I booted my Win 10 today and started Firefox. All of a sudden I got the "warning" in the title. The add-on was Search and New Tab by Yahoo. I looked in my installed applications and right at the bottom I had a newly installed application called Yahoo Search Set. Needless to say I didn't install it.

The problem with the message above is that it doesn't provide enough information about who's trying to install the add-on. Yes, in this case I got it right but what are the chances of an adware or other malicious piece of software (I view Yahoo Search Set as well as the Firefox add-on as such since it installed without me saying so) announcing itself in a clear way?

Is there a way to find who is trying to add something new to Firefox (or any other mainstream browser for that matter)?

  • You can always try to infer the program that carried the malware using the install date. – Daniel B Aug 3 '17 at 8:10
  • Unless other software was installed after the malware installed itself, which will make things more difficult. I was looking of a more straight forward method without the need to manually check the list of installed software. – rbaleksandar Aug 3 '17 at 12:09
  • ? Windows records the install date of all programs. Unless something else was installed on the same day, you’ll be able to narrow down the search a lot. – Daniel B Aug 3 '17 at 12:16
  • "Unless something else was installed on the same day" I'm looking for a solution that is independent from the time the malware installed itself, how it's called etc. (basically everything that involves manual search no matter how small the effort is). – rbaleksandar Aug 3 '17 at 13:30
  • You may try AdwCleaner from Malwarebytes. – Biswapriyo Aug 31 '17 at 9:49

I would bet real money that it came from installing Java.

If that's not the case, you might also want to check for the presence of Spigot on your machine.
