Doesn't matter if you use the trackpad or not, it's still there. If, for example, you have a swollen battery, it will still impinge on the trackpad and cause spurious inputs, regardless of whether you have another mouse connected or not. The same is true of most of the other possible trackpad-related issues.
So how you do explain files that have been moved.
A trackpad or mouse causing spurious inputs can easily do such things, and can easily fool people into thinking there is a purpose behind the random movements. Seeking patterns is a natural human tendency, which can sometimes cause us to see patterns where none exist.
Or the time (about 3.5 years ago) when a client contacted me and as I needed to review previous emails there was no content. All text had been removed.
Corruption in your mailboxes. I've seen this one myself before. No need to summon up a hacker to explain it.
Or my accounting program in finder that used to have an icon now has a black box?
Why would a hacker want to change the icon of your accounting program? The app may be corrupt, or it may have code to change the appearance of the icon that shows in the Dock and that code is no longer functioning properly on the version of Mac OS X you're running.
Ultimately, it doesn't seem we're getting anywhere with this. You seem to be rejecting potential solutions without trying them, because they don't fit the preconception you have developed about what is causing the problem, and so there's really nothing we can do for you here.
