Carbon Copy (software) Carbon Copy was an early remote control and file transfer software for DOS and Windows published by Microcom. It allowed remote access to a computer via dial-up modem connection.
A viral infection (the common cold) is the most common cause of a stuffy and/or runny nose, but allergies, influenza, and sinus infections also may cause these symptoms. Less commonly, anatomical obstructions (e.g. a deviated nasal septum, foreign bodies) may lead to nasal congestion.
One of the most common characteristics of chronic rhinitis is post-nasal drip, which is mucus accumulation in the back of the nose and throat that drips downward from the back of the nose. Post-nasal drip can cause sore throat, cough, or throat clearing. Treatment for rhinitis includes avoiding allergens, medications (both over-the-counter and prescription), and irrigating the nasal passages. Surgery is a last resort to correct any structural issues in the sinuses that may be causing the symptoms.
