I was using my LG LG-L38C with android 2.3.6 to find directions on the web when this screen came up that reads, "the page at 'http://antivirusandroid.mobi' says: Memory Warning! Your phone has (7) serious errors! Press OK below to start the recovery process..." the back button doesn't work so I cannot use the browser and I don't want to press the "OK" button without knowing what this is. Also my provider is straight talk wireless. Please help.
