Which is why I attempted to emphasize "should" meet the requirement of evasion to be an effective virus. The first two items (searching, copying) are critical points in the definition of the term virus. It doesn't have to be a large and sophisticated search function, to effectively replicate however. You're spot on as far as I can tell in your definition of a worm. Once a virus cross the threshold of a network, its defined as a worm, with basically the same function as a virus.
The point I was trying to get across, and I may have not communicated that effectively, was this so-called virus is more like a copy protection scheme than a virus in any sense of the term. This particular Brain program degrades system performance, and attempts to scare the end user triggered by the act of copying the program it is trying to protect. It loosely meets the definition of a virus because it meets the requirement of self-replication. Its an ineffective virus because it does not meet the tertiary requirement of evasion. I'm comparing it to a copy protection scheme, because although it can self-replicate, the intent of the program was never self-replication. Rather this Brain virus actively discourages its own replication in order to protect another program from copying.
