What is (random-characters).exe?
I frequently get questions asking “what is qwijbo.exe”, where “qwijibo” is
what can best be described as a random assortment of characters. Examples
include wfwvkdyl.exe, tjuazuyt.exe, and others. They key is that the name
appears completely nonsensical.
What are they? Hard to say. But my initial guess doesn’t bode well.

My belief is that these are manifestations of viruses (or maybe
spyware). Several viruses are known to generate random names for the files they
leave behind on infected machines.
My advice as always is to get a good virus scanner, keep the virus database
up to date, and scan regularly. Same story for spyware.
