Perspective -- just about every virus, trogon, or worms performs a certain degree of harm and it just depends on the severity of it whether you should correct it now or it's something you can live with:
1. You have an irritating squeak in your car. It's undesirable but something you can't fix and the experts -- who went to school, spent lots of money doing so and has no common horse sense, at the dealer want an arm and a leg. A Shade-tree mechanic -- who has no formal education and knows everything about anything that didn't cost a penny, can fix it for a little of nothing but you get no guarantee.
2. You have something knocking in the engine and just know it's going to fall out. You don't thing a Shade-tree mechanic can fix it reliably with warranty so you have no choice but to take it to the experts and pay dearly for it because they have the resources and training.
3. You're simply not going to find a happy medium where a single utility has been written that combine the scenario between a Dealer and a Shade-tree mechanic which combines all things together in one -- too complicated for one and isn't important enough for the other, unless you're extremely lucky. This is why you're going to find different strokes for different . . .
4. And for your reading pleasure, "What are parasites?"
