A hacker somehow got hold of my email address list and sent everyone the message to check out a linked web site. I did not—and would not—click on it to see what it was about, but I suspect it is an ad for some sort of employment. (Neither do I respond to widows of Nigerian Ministers of Finance.)
If you got one, the email had “Hi” for its subject and my name as the sender. I restored my system to a date before the email and ran a full scan that showed no viruses on my hard drive. I am guessing the hack could have been at Yahoo! that handles my email (via Verizon) and there was nothing I could have done to prevent it.
I do not think your computer would be infected, even if you did click on the link. The Windows operating system is much more robust than it once was, and a rogue program cannot install or change your computer without your permission. Just be wary of email from anyone that does not “sound” like them. Weak advice, I admit.
On the positive side, I have heard from a lot of people I thought were dead, and some I don’t even remember.
