Here is what I would do from an my perspective.
-
Run the link through Virus total, and have it reported
VirusTotal -
Run malwarebytes with a scan on your phone for safe measure (or make sure you use what is available to you like Eset, Sentinel One etc…).
The only good open source clam AV which is also a good alternative if this is also wanted and on android
- Only open links in the browser that has ad block (Ublock) and enable HTTPS only mode. This can be done on Firefox and chromium browsers.
If this is on IPhone, this may be different as I believe that prohibit this as far as I’m aware for extentions as android do this.
- I would also change the password if that specific account and any accounts that may have been signed in to on the Facebook browser, and mass sign out from facebook, and clear the cache, cookies and delete and reinstall the app from official sources only.
