THE PAST MONTH has seen major developments in fake antivirus software for Mac OS X, but an alert from security firm Sophos shows that criminals haven’t forgotten about trying to make things trickier for Windows users.
The security firm came across a scam where criminals detect a user-agent string from a web browser, displaying a fake Firefox security alert after detecting that a user is browsing with Mozilla Firefox.
On this alert there’s a place where you can click ‘start protection’, which will download a fake anti-virus program that you can register for around $80. Experienced Firefox users will already have realised it’s a scam, since the browser doesn’t actually have a virus scanner.
