I was browsing the web yesterday when suddenly both my CD and DVD drives opened by themselves. I read somewhere that this is a sign that a hacker has control of my PC - is this true? If so, what can I do about it? I've got McAfee Firewall and antivirus software so I thought I'd be protected.
I may be worrying unnecessarily, and it hasn't happened again since, but if anyone can offer any sensible advice I'd be grateful.
