I often receive emails like this I always ignore messages like this because I know this is phishing but sometimes it's annoying almost once a week I receive emails like this, I also wonder why the scamerr knows my email even though I didn't publish it.
This is exactly what is needed to be done once you recieved an email that you can't recognize from whom did it came from. Ignore it as much as possible because the possibility of unknown emails to be a scam. virus, phishing, ransom ware and al the malicious software and sites is very high. The moment it instructed you to install something, you should question its intention and purpose. Never trust and never ever install something from anything unknown. Never compromise the safety of your device, your asset, and yourself
