First off, I'm not COMPLETELY computer illiterate. I built my own pc and have a decent understanding of how stuff works. But when it comes to security and software I'm a little lost. I have avast and have never had any problems before. The other day, I got an odd error message saying that I needed to restart my comp because of a driver failed or something. Thought it might have to do with my keyboard, since that same day I updated the firmware. Today, I tried to access my task manager, and it opens for a sec, and then shuts itself down.. I ran a scan and nothing was found. What are the general steps one needs to take to make sure their computer is secure? I'm running 8.1 if that helps at all..
