But there many legit programs that are bundled with other legit (free) programs. Similar to UC Browser, Baidu AntiVirus, some User Install it on Purpose, Some user get it with bundled.
AntiMalware (like ) are more aggresive than AntiVirus in blacklist a PUP, maybe because AntiVirus focus on Prevent and AntiMalware focus on cleaning.
In case of PUP, we can't trust AntiVirus 100%. Only User can know what program is installed on purpose and what program is install with Bundled. AntiVirus just can detect a possibility. That's why we need HIPS because it based on user decision.
@TheMalwareMaster, can you send Utorrent installer file to us that contain ByteFence? I just downloded it from official but not bundled with ByteFence. I want to test how HIPS React with this situation.
