Hello,
Thanks M-K-D-B, sorry for misunderstanding.
@Simplex: Can you zip me the folder "C:\Users\Admin\AppData\Roaming\Mozilla\Firefox\Profiles\41A66E7E5EE1" and your profile: "4ui6vnjc.Simplex" ? I'll merge the two so that you'll find a clean profile, and you will be able to clean with AdwCleaner the malicious one.
Thanks,
