I hope it's not infected, but if it is don't throw it out. Experiment with it, you may have more infected batches in the future. When I had an infected IPA i tried lots of things to make it drinkable; adding juice, adding juice concentrate, vodka "bad idea." But in the end i found coating a frozen pint glass with lemon juice, like vermouth on a martini glass, and turning the glass a complete 360* while i poured made it a lot more drinkable.
Actually it was a whole lot of drinking bad beer, to get to the point of drinking "not that disgusting of a beer." So maybe you'll just want to throw it out. But hopefully it just needs more ageing! Good luck.
