Hi Thank you! See what happens in the future. Still using the latest V6 of avast. Is stable again.
I would do a scan of your USB stick also just in case…Also I think to my knowledge that this JS Script launches itself from an image or a jpeg image…when clicked on …As I remember correctly I did a Malwarebytes scan …while Malwarebytes was scanning Avast Ball was turning or checking the files scanned by Malwarebytes also… and picked up the reminants of this JS Script…Luck and keep us updated…
