The way a virus works is it attacks the receivers email and then sends itself out to everyone on his list and then the next persons list and so on. Look closely at the email that told you this and check the senders addy. I get scam maill all the time saying this acct or that acct was possibly hacked, but it will say pay pal or amazon, but the senders email is like ryeeryawew7s99900rtyhgee0rr0 or some such bs.
Download and run malwarebytes and see what it says, use the free trial and make SURE you get it from Malwarebytes and not some third party. You might find you have some pups, which may or may not be bad, it means possibly unwanted programs.
It sounds like BS to me. People have gotten wise to the phone calls saying you are leaking viruses, personally I loved messing with them, they say they were tracking my IP, but I'm on a VPN. When I ask them what IP they were tracking, they give me an IP that shows up when you check connected IP's on millions of computers, it's a router and you can't track that unless you are logged into it. I'd try to keep them online as long as possible, I'm retired and it's entertaining to make them dance for me.
