I would distrust the softwares homepage in any and all intances.

Going by the tenebril site, this dosent seem to be a major problem, and since its installed by AoL, its probably not as badly written as your average hijacker or what have you (AoL do suck, but not to the extent of crashing every users PC. Not regularly at least).

So, your choice. I'd kill it on general principle, since it is running in the background and eating valuable cycles, but you could leave it without major consequence.
