Mike, I've confused you .....
Malwarebytes is on my PC NOT my Chrome book. Chrome books don't get viruses - one of the main reasons I opted for one !
However, when I bought the Chrome book, I decided to download the Chrome browser onto the PC ..and synchronised the two --- everything was fine until the Search Ya thing appeared on the PC in the Speed Dial pages ! I got rid of Speed Dial, did a scan with Malwarebytes (on the PC) and got rid of the nasties.
Because the synchronising had put Speed Dial onto the Chrome book I was bothered that it too may have been affected ...BUT it hasn't - also there is a very good back up team with the Chrome book who replied almost immediately to my query about this, thus alleviating my worries about the Chrome book.
The flipping radiio 5 live problem is still there
I think it's going to be a long job. I can get some of the R5 Live listen again braodcasts, but not all ....? Still can't listen to PMQ's from last Wednesday ---
Thanks again, don't go to too much trouble re Firefox ..I'm happy with Opera 12 and the Chrome Browser plus my Chromebook ... It's the radio things that's hassling me - but hey ho !
