Hi, for the future, try installing this ad-blocker which is known to help prevent malicious adverts: https://addons.mozilla.org/firefox/addon/ublock-origin
To check for malware that may have been installed, open the 3-bar menu > Add-ons > Extensions, then look for and remove/disable anything you don't recognise. Restart Firefox afterwards if you made any changes.
You can also check your Firefox Desktop shortcut for corruption: Right click on it > Properties, and in Target, make sure there is no sign of anything other than Firefox. If there is, delete that part of it. Or if it's easier, you can just delete it and recreate a new shortcut. More: Wrong home page opens when I start Firefox - How to fix.
In case some malware has already been installed on your PC, you can try scanning with these free programs which work with your existing antivirus software:
- Microsoft Safety Scanner
- MalwareBytes' Anti-Malware
- Anti-Rootkit Utility - TDSSKiller (for more info, see this alternate TDSSKiller download page)
- AdwCleaner (for more info, see this alternate AdwCleaner download page)
- Hitman Pro
- ESET Online Scanner
