Today on a normal navigation with firefox a fake popup said

"your firefox is infected with 2 virus"

then android ask me to give to firefox the "vibration access" of course i refuse. And then firefox ask me to going to google-play to download antivirus.

I deinstall firefox and reinstall..and the page with advice disappear.

I download then the "free antivirus" from google-play(not the antivirus wich firefox want to force me to download) and do a scan..no virus found.

But now with linux I do a nmap on android device..and port 554(rstp) tcp is open! Why is open?Is my device infected or what else?

  • Delete the browser cache and it probably will vanish as you discovered after re install. It does not mean that your device infected. You may like to run a scan using Malwarebytes app from play Store.

Solution found,there is something strange on my net because i see 554 port on every machine!

But if i did a telnet outside this machine..554 doesn't answer.

I investigate..meanwhile i'm happy my android is not infected,firefox probably take a fake virus.
