Try installing Malwarebytes free version and see if you can get rid of the malware. Restore points might not help. If the popup is only in the browser, install another browser and try that. You can have as many browsers as you want. Also open the options in your first browser and make sure popups are blocked. To see more restore points, increase the space available in System Protection. If the space is not big enough, you will have room for only one restore point.
I am running Windows v 8.1, would like to go back more than one restore point, and cannot do so. Any suggestions? When I click System/System Protection, click the [System Restore] button and choose the "Choose a different restore point" radio button, I am only offered a single restore point. I understand that some users also see a radio box reading "Show more restore points," but I have no such option. Is there a download available or some other way to see more than one restore point? I tried restoring in the hope that I could then see a prior restore point, but not such luck. The reason I need to do so is that I'm getting an annoying malware pop up in my browser and going back a restore point (or two) seems to be the only way I can find to make them stop displaying.
