Millions of Android devices remain vulnerable to the Heartbleed bug a week after the flaw was made public.
Google announced last week that handsets and tablets running version 4.1.1 of its mobile operating system were at risk.
The search giant has since created a fix, but it has yet to be pushed out to many of the devices that cannot run higher versions of the OS.
It potentially places owners at risk of having sensitive data stolen.
In addition security firms warn that hundreds of apps available across multiple platforms still need to be fixed.
