It looks like SEP is detecting Trojan.ADH, and quarantining it.
What are the full file names, and the original locations of the files? The columns for those are very narrow, so the full path is not visible. In the Risk or Scan logs, how were these files detected (for example, Auto-Protect, Full System Scan)?
What version of SEP do you have? Are logs filling up your drive, or is it the contents of the Quarantine itself?
From the Security Response write-up:
"Trojan.ADH is a detection technology designed to detect entirely new malware threats without traditional signatures. This technology is aimed at detecting malicious software that has been intentionally mutated or morphed by attackers."
(Emphasis mine.) I would also double-check that all Windows Critical Updates are applied, and third party programs/plug-ins such as Adobe Reader / Flash / Shockwave, Java etc. are all at the latest version. If these are all really malware files on your machine, you may need to patch a vulnerability.
You can also use the SEP Support Tool's Load Point Analysis and Power Eraser for further identification (in order to submit) and eradication of suspicious files.
