WIFI connects, will not open any internet pages

WIFI shows full connection but a few days ago it started not opening any internet pages or accessing my email or any other internet accounts. Could this be a virus and if so how do I correct it.?

I have reset wifi,cleared known networks, closed all internet tabs, powered down and restarted,logged in several times. No success. Next step is the factory reset. Does this affect my phone account and if so how do I get it back on ?
