I have preferred Kissasian before, but my antivirus software keeps warning me about the site trying to load unsafe content. 

I've had the same problem with dramacool too.

What other free sites do you guys use, where you have not had this problem?

Prefer apps if u want to play safe

Please tell me an app!

Have you tried the free content at (Rakuten) Viki?
BiliBili might prove fruitful (like YouTube, an adblocker is essential for this one).
