Site change while reading

I've been having this problem for the last couple of days.

Upon opening the first manga of the day, staying on the first page, not touching anything, in about 1 minute tops, the site changes automatically to ixxx.com.

Not showing as a pop-up on my javascript popup blocker, I don't agree in the least with having the site change, on it's bloody own, to a different site, without any sort of input from me, except for the fact that I've decided to read.

I have a problem with this because I have the chance of clicking right after the site switches, sending me who knows where.

Use ad-block. If that doesn't work, it might be malware.
