Norton 360 downloads fail

I can't get downloads to finish downloading.

 

I used Firefox , but they have blocked javascript  downloads I can still get videos if I download to desktop and play
them before they are finia\shed downloading.
Other downloads, from my bank, I can't get out the download area.

 

ie 10 is junk, ie 11 won't even download.

.
So, I've gone to google chrome,.I tried to download Adblock Plus, virus scan has Failed .

 

See my aattachments if I can get up here

 

I can't figure that out ."how can I post if there no way to post"?  ...the attachments  are approved
