Threat secured pop-up will not disappear

[REDACTED]

Hi there

(New to the forum and did search for this.. but couldn't see a solution)

I've picked up a tojan called JS:Agent-DZX on my WP website. I know this because Avast told me.

"Threat secured" it says
"We've safely aborted connection...more threats might be lurking, scan my PC"

So I scan the PC, but the pop-up notice keeps appearing. I try to X out the message but it keeps coming back. I drag the message to a different screen, be a short time later it reappears.

I cannot get rid of this message.

Any ideas?

Thanks
