This sounds like your password ***** have been compromised. You will need to do a power wash on the chromebook.
Follow these steps please>while on the sign on screen, press Ctrl+Shift+Alt+R at the same time. Then press Restart. When you restart you'll be presented with the start screens. -
The screen connect is optional. You do not need to pay anymore. The Chromebook will now work as normal.
Please reply and let me know if you need any other assistance or if everything is good, take a moment to rate my service by choosing one of the stars at the top, then click submit.
Thank you very much!
Everything that you had backed up will restore when you sign back in on the Chromebook. You don't need to get the virus checked, the power wash removed all malicious programs or viruses.
Do you need more help with this?
