1 9 days ago BT virus/malware scammer - wants you to log into your computer, then likely download one of their apps to 'fix' problem that doesn't actually exist on your computer but if you follow their instructions, you will soon have their own malware on your system which will jeopardise your data security (e.g. payment card details, identity data, address etc). DO NOT ENGAGE WITH THEM, JUST HANG UP! BT/Windows will never call you like this. Responsibility for securing and maintaining your computer system and data lies solely with you e.g. antivirus software.
