BEWARE ! : FBI warns not to upgrade software through free-WiFi !

The FBI has reported that users of ‘out-of-home-WiFi’ (free-WiFi hotspots, hotel WiFi, etc.) have become infected with malware, while upgrading ‘a widely used software product’.

If the user clicked to accept and install the update, malicious software was installed on the laptop. The pop-up window appeared to be offering a routine update to a legitimate software product for which updates are frequently available.”
