I have a friend who bought Bitdefender Total Security 2016 online. When they click on the link emailed to them they could not get it to install. So they called one of the 800 numbers from the support page on the web site. The guy on the other end takes control of their computer and then claims that their IP address has been compromised and something about a trojan (by the way this is a clean install of Windows 10). He then claims that they need to install some software on their computer to fix the problem and that it will cost them over $400 (can't remember the exact amount). This totally sounds like a scam to me. But I am sure they called one of the USA support numbers from the Bitdefender web site.
Any advice?
