What to do next? Several times got warning from avast of aborting connection from Chrome and Firefox for Avast aborted connection on cdn.dna-delivery.com/dna-client/6.5.1/peer-agent.js .
Scanned with Avast and Malwarebyte, no viruses ir malware found.
How can I detect potential reason for this warning and get rid of that? Is it possible that I have any virus or malware that creates that or is it just from opening some specific web page? I have suspicion on one specific page.
