I have an acer aspire that I cannot complete a virus scan on. I have tried AVG, Avast, Malwarebytes, and avira and they all freeze in different spots. I upgraded to Windows 10, hoping that might solve the issue but it hasn't. On top of that when I let the laptop sit idle for more than about ten minutes it restarts. It's also going extremely slow. My 7 year old was playing webkinz tonight and it was lagging very bad whereas it used to work perfectly. Any advice?
