Yesterday everything was fine, but today my antivirus screams in fury when I try to enter, for example, 'Posts' or 'Uploads'.

'JS/Adware.Agent.AC' is the thing to blame. The hell is going on?

You needa provide a bit more data if you want help. What antivirus and browser? OS? Using adblock or ublock? If I had to guess it might just be a new ad.

Google Chrome and Eset Nod 32, but... doesn't matter anymore. It works now, begrudginly.

Cringe, ESET decided to mark the entire ad network we use as malicious. Even though its one of the biggest one in the world, also out of 50 antiviruses only ESET done it. Instead of actually apologizing for its false positive went out and trash talked the network some more. If you want to cringe some more you can read it here: forum.eset.com/topic/1662...-want-to-enter-kissanime/

Gosh and they blame exoclick for this, even they closed the treath just because they can T_T
