Thanks for the reply and the opinion of PCMag. I already use Avast and in fact ran an online scan from Trend this morning and it found nothing. I have also run a full scan using Malwarebytes that has in the past picked up and removed undesirables! Not heard of Avira so will have look.
More to the point, what do these "threats" indicate?
