Does [Susp] mean Suspected or Suspicious? Or something else?

Avast’s Web shield blocked two different postimg.cc links (but still let me view the images themselves which was odd) because it claimed the pages were infected with HTML:IFrame-inf [Susp]. Now Avast did claim to block it, and I did both a Avast smart scan and Windows Defender quick scan just as preliminary measures which found nothing. I’m about to do a full scan with Avast right just to be safe (and i’m about to go to sleep any way). But I’m curious what that [Susp] part means and if it’s Avast saying that if it’s Suspected or Suspicious maybe it means they’re just being cautious?

Suspicious

I think it is placed as suspicious but I think a copy of this file goes to the Avast servers to be analyzed after an analysis it may be on the blacklist or not, I think it is like this, as the vast majority of antiviruses do .

Well it doesn’t look like a file made it onto my computer, it was a website that was blocked.

Avast virus scans came back clean, by the way.

I have never had anything go into this folder, although plenty of emails I get could have been there. Is there a way to submit an email so Avast can get their shit together?
