Malware/trojan infection. (JS:Trojan.JS.Agent.TRY)

Ran a full scan with Bitdefender (yeah... I know. But at least I have a scanner).

During full scan, it found these:

Should I be concerned? Were my passwords and other personal data stolen? Maybe some remote-access trojan was installed? Or is it false positive?

I ran EtreCheck several days before, but no such things were detected. And I ran MalwareBytes (free version) before running Bitdefender, but did not detect anything.

Thanks in advance.
