I had trouble getting my new Outlook settings correct to communicate with my ISP. A quick search lead me to a bogus phone number for Verizon help - 1-866-666-5542. They connected to my new computer (HP 110-210 64 bit Win 8.1) and through a few command prompts produced a "tree" in the dos window that showed "zeus trozan"(not Trojan), at the very bottom. Claiming that all my network devices were now infected they wanted me to take them to a specific address and leave them for 3 -4 days and hundreds of dollars in cost. When I said I wouldn't be taking the devices anywhere they offered to fix it on line, again for hundreds of dollars. Believing I was being duped I cut the connection as quickly as I could. I have since run the Microsoft Malicious Software Removal and it found nothing. Is this tool and Windows Defender enough to ensure that my computer is malware/virus free?
Thanks in advance for your support,
