champion.gg uses stuff they call adumen and adonis to load ads from www.adumen.com via xhr - and it replaces the whole page to "disable your adblocker" if you block that xhr connection to adumen.com (observed via umatrix)
Additionally they obfuscated the javascript.
Blocking the created dom elements is impossible, because there is nothing to identify them.
Would be nice if someone has better news, but I think to block ads on champion.gg, an update of adblock plus is needed that can do better stuff (don't know how to block it)

I cannot reproduce the issue.
Use only 1 adblocker, test again (disable umatrix for that site)
Tried disabling all other Chrome plugins I have and all other ADB filters, acceptable advertisments are off.
Ads still shown (they load about a second after the page).
In Chrome Easylist+Easylist Germany is active, in Firefox, Easylist is active in the settings.
As I do not see advertisments and ADB is working on other pages like youtube, I do not think I am infected with any malware, like the ADB help forums you linked potentially say. I am also using avira antivirus and do not have its chrome extension installed. chrome://plugins is not existing.
Chrome: Version 60.0.3112.113 (Offizieller Build) (32-Bit)
Firefox: 55.0.3 (64-bit)
Disabled Avira, updated filter list.
I can't create an issue report, I am getting error 0x805a1ff5.
I copied the report data and put it into pastebin.com/4CTtmGs9
