Windows Defender Scans. Windows Defender has two scan types: a quick scan, which looks for viruses and threats in areas of your computer most likely to be subject to these threats; and a full scan, which checks every file in every folder on all of your hard drives for threats.
The most common causes of lymph node and neck pain are infection of some variety, though swelling and inflammation owing to injury elsewhere may also be to blame. At least in humans, some of the most prominent lymph nodes are located just behind the sinuses and in the soft tissues of the neck and upper throat.
Extra traffic through the lymph nodes--when there is some kind of condition causing an increase in inflammation--will cause these lymph nodes to become enlarged. There are many different things that can cause enlarged lymph nodes, including infections, auto-immune diseases, and even some cancers. It can be very unsettling to wait to see your physician to discuss the results, but you have taken the most important first step--seeking medical attention.
