when I click on links from some trusted emails, the required web-site appears for a few moments, then it gets "hijacked" by a site which appears to be of Russian origin (at least the language looks like Russian). It then stops me from accessing the required web-site and takes me to what appear to be porn sites. I close it down quickly but it has happened several times. I turned Java off and didn't seem to get the problem although that might just be luck, but then the required web-sites don't work properly, when I turned Java back on it's just as bad again. Reaching unwanted porn sites is bad enough but I can't access the sites I want to reach either. I'm not very technical but I thought Ipads didn't get viruses, can anyone out there help me to solve this please?
