Virus locked Chrome OS -error 0x80040201
Hi, I am pretty new with Chromebook OS, used it for 3 months without any problem. But Today I got a virus which locked my Chrome OS. A strange Windows related message 0x80040201, ask me to call a 800 number, the person answered the phone wants $99 to remove the virus. I have 2 users on my Chromebook, one is the owner user, the second one is just a user. The owner user is locked, but the second user is still OK. I can sign on to the second user to use the chromebook still. Here I have 2 questions: 1) How do I remove the virus from the Owner user ? 2) If I can not remove the virus from the owner user, Can I make the second user as the owner, and delete the original owner user ? Any help will be appreciated.
