Several times when I've gone to links within threads I've gotten this:
The page at www.mobillean-tivirus.com says....and then it tells me my phone has 13 viruses and to follow the instructions to remove them. Needless to say...I haven't.
It looks like there's a dodgy ad somewhere on AB: http://www.androidauthority.com/mobile-scareware-ads-338182/ Email the Ed ( theeditor@theanswerbank.co.uk ) to let him know about it.
If you are still seeing this, could you try clearing your cache and see if that solves the problem? Also if you see the same thing but it is coming from a different web address, could you please let us know what that address is? Thanks!
