can you pour one of your bottles, let it warm and degas and take a gravity reading?

like Revvy said, many times new brewers are anxious to try their beer, drink a bottle of green beer and get overly worried. most infections will cause your beer to continue to ferment down near 1.002 or lower. if the gravity is stable and on par with the gravity at bottling time, it's doubtfully infected. green beer can taste quite tart from the yeast still working on the priming sugar.

Looking back on previous posts.... I would say give things more time. Sounds like sour, green beer. You can hit your gravity in a short time ,but the yeast has to clean up to make decent brew.

Since you're just starting in brewing, knowing how to describe the flavors of your beer is really helpful to the more experienced brewers on this site. Here's the classic wheel of flavors:
BT - An Introduction to Sensory Analysis {flavorwheel]

And a page which attempts to explain how to use it:
BT - An Introduction to Sensory Analysis

I've had to do tastings of my questionable beers with this printed out in front of me, and it's really helped.

Thats a good point, Acetalaldeyde (Green apple/ jolly rancher flavor) can come a cross a sour note. I learned this in my BJCP prep class the other day that Bud light has a good amount of acetalaldehyde in it. A good test might be to get a bud light, and give it a good smell and taste. It comes on very strong the first taste. Think about green apples or green apple jolly ranchers, and it will be easy to pick up on.

If this is the sour flavor you are getting it is likely what Bob is talking about, beer that was racked off the yeast cake a little too early and is a little young.

One thing to taste for if you have an infected batch is Diacetyl, butter flavor or the feeling of a slick coating on your tongue. Souring bacterea like pediococcus or lactobacillus will produce a lot of diacetyl so if you have an infection with a souring bacteria you should detect diacetyl's presence in the beer.
