Video & Audio advertisements in my opinion are not malicious unless they are made ugly.

Likewise websites: harms my eyes or my common sense of beauty -> malicious

No, for real. IMHO a site is malicous when it does serve software that harms your computer by installing fake codexes, spyware software, trojans, virusses, backdoors etc on your computer/phone or makes use of click-highjacking
