To be honest, you need to question more thoroughly what could be happening here.
If this "deletion of files" was a common occurrence, we would have heard about this a lot more, but we haven't. That implies something specific to your system, and more specifically these files that you say are safe.
What are these files? How do you know that they are safe?
You seem to have had issues installing various anti-virus software before....cant install any antivirus....it sounds to me like there are deeper issues with your system.
