Sounds like some kind of dropper (virus) that's opening webpages, and has gone undetected by avast.

Try doing a virus scan with malwarebytes (be aware, cracks are reported as false positives with this scanner), and double check your browsers for unwanted extensions / addons.

If neither of those work, all I can suggest is resetting your dns settings, and installing a different virus if Avast is the problem. These are unlikely to be the problem, however.

As a last ditch, backup your personal files and do a fresh install of your OS.
