Anti-virus keeps popping up with the same message every few minutes, what is wrong with my computer?

You have too many different security systems, each one considers the other an invader because each leaves a small computer file that is unrecognised by the others. I suggest that you UNINSTALL (do not simply delete) duplicate security systems and keep only one. I recommend Norton Symantec as the most reliable and comprehensive security system, it is not free but worthwhile. My first computer, which was much more expensive than they are now, was destroyed by a virus. Good luck Gladgran
