This is a number on my caller ID used to call from a company so-called Southend Enterprizes. They want to show you all the problems of errors and warnings in your computer. Then he wants his IT department to take over your computer with your permission. Being skeptical, I would not do it without some confirmation of who they are. The rep gave me the number 210-888-9112. Once I looked up that number it only confirmed my suspicions. These reps have VERY heavy accents and are hard to understand. Be cautious!!
