I have recently received 3 calls from someone who says my IP address has been compromised and I need Dell support to take some sort of action concerning my PC. I don't say on the line too long to get much detail, I reported this to Dell Support after the first call but have not heard back as to response. The phone number is the same each time 315-288-0664. The caller has not mastered the English language so it sounds very fishy. Has anyone else had this call or is it by chance legitimate?
