Help ACER ASPIRE ONE SERIES wont work?

Well when your Acer Aspire turns on tap F8 very fast until you get advanced startup options and choose safe mode with networking and download Malwarebytes and run a scan. If Malwarbytes does not work search for System restore and use it. If you can't find system restore in safe mode restart your computer,tap F8 and startup with just the command prompt and type the command rstrui and press enter and wait a minute.
