I downloaded some pdfs from there and according to virustotal and some pdf online scanner i tried, they have something possibly malicious going on in them. I already deleted them but i opened them in firefox pdf reader. I dont have acrobat installed.
Scanning my system with malwarebytes now, but nothing is finding anything wrong and I havent seen any suspicious activity.
That virultotal report looks completely fine to me, including the behavior tab.
Regardless, imagine what would happen if the firefox pdf reader was vulnerable to a well-known attack (of course there probably exist 0 days but they wouldn’t be burned on you). Any attacker could simply link you a PDF and you’d be infected simply for clicking the link? If this was true, people would stop using firefox because it would be insecure.
