the problem i will mention appeared the last 10 days. when you click from firefox via google search my site, some of my visitors, not all, but a big number taking a popup window with titan poker (newsblock). if they visit direct my site (and not by clicking it via google results) they don't anything. also in first case, all they show that, said that they are not taking all the time. will be happened for example 3-4 times a day. the next day maybe not take anything, and then the other the same issue. we tested all the diles of wordpress with my host provider and a wordpress expert.there is no malicious code in the files (wordpress+themes). as i am saying again these problem is not from all and also only happens via the goole results and only with firefox.not problem with chrome mentioned. my host said that maybe these users who taking have a malicious extensios in the browser. but all 10 users who have mentioned the problem, perhaps there are muchh more who didn;t tell anything about these yet, is it logical to have all malware? if anyone saw such a kind of issue ever, or it thinks that has a solution, i want to read he/she advices. thank you!
