I have a Dell Inspiron laptop running Windows 8. The McAfee antivirus programme was pre-installed on it and was working perfectly fine, but now, suddenly it shows up as "software not set up" in the hidden icons tray. It seems to running perfectly fine, though. Should I be worried? Lately, my computer freezes quite frequently, and only a hard re-boot can rescue it. Is the computer infected or about to crash?
