Getting akamaihd.net search website when I log on with updated Firefox. VERY ANNOYING.
I get this automatic website when I log on in stead of cursor going to search box so I can enter question. How do I delete this?
As you've already suspected, you've picked up some malware that you will of course want to get rid of.
Go to the Firefox menu (≡) => Preferences => Add-ons => Extensions and remove anything that looks unfamiliar or suspicious.
Next step is to run malwarescans - further information can be found in this article :
Run most or all of the listed malware scanners. They all work differently - what one program doesn't pick up, the other might.
