Been asked several times over in the last months if you take a look at the first page of this section. The best answer still probably remains this however:
Yeah, I'm going to call horse feathers on this. First, as I said in my thread about this issue, I make my living doing tech support. I deal with these issues on a daily basis, 5-6 days of the week. Second, IF my phone was infected, as this person is claiming, then I would be getting these adware & malware issues on EVERY website I visited on my phone, not just this one. I use my phone on Twitter, Facebook, CNN, & Google News on a daily basis, & this site is the ONLY ONE that was consistently giving me that hijack issue.
So, Occam's Razor states that the simplest answer is usually the correct one. So, either every single person who has reported this issue is involved in a massive unknown ad scam, or the simple truth is, NarutoBase has a problem with malicious ads, a malware/adware infection, or both.
