Chainstay on drivetrain side scratched within a week of new bike?

Hey everyone. I just bought a new bicycle last week. It is actually my first "real" bike. It's an entry-level 21 speed Schwinn Searcher (hybrid-type bike) with an aluminum construction frame. I just wanted to get a bike for recreational riding around the city.

However, just recently, I noticed that my chainstay on the drivetrain side (on the "right" if you will) is scratched already. The scratches are semi-bad, but just on the surface it seems. The scratches are also located more toward the front derailleur which leads me to believe that it's getting hitting toward more the front gears or that's where the chain is slapping onto the chainstay. However, the scratches have ruined the frame's paint already.

I think the chainstay is scratched because one time the chain went the wrong way (kind of like a mini "chain suck") and became tangled within the gears and chainstay as I was shifting. I then had to manually rotate the pedals backward and somehow got the chain back to normal. I guess my questions are as follows:

1. How do chainstays on the drivetrain side usually get scratched or messed with? I noticed my girlfriend's bike has some slight scratch on hers too. It's not as bad as mine, but there is still some scratch. Is it because of the chain hitting on the chainstay as one cycles onto a bump? I do occasionally hear a "cling" sound every time I go on a steep bump and back up to regular pavement again just from normal roads. Could this be it? Or are the chainstays usually scratched from something more major like chains getting stuck within the gears and frame?

2. What is the best way to fix or prevent this? I researched the forums and it seems there are "chainstay protectors" and guards-alike that protect against this. I am not sure how many people actually use these and whether they're worth it or not. I am not sure if these protectors are even good for the chain? Should the chain be hitting them even at all? Should I just leave the scratches as they are...? I guess I can never aim for a perfect looking bike. It just seems scratches are norm.

Thanks!

Ah, yes. Thanks! That's probably what I need. I found some of them (or similar) at my LBS. I guess I should always purchase these every time I get a new bike...I'm quite the paranoid when it comes to trying to preserve my bike as much as possible.

However, I still don't get what's can actually cause the chainstay to be scratched. Is it all that common?

In most gear combos there's not enough chain tension to prevent the chain from hitting the chainstay over bumps etc. Especially in smaller chainring/gear combos. The tension will vary the most with triples and huge rear cassettes.

This is not unusual nor noteworthy.
