Unless you want to have your ID stolen, spam emailed to your email list, or to receive popup ads and spam, don’t impulsively click on links!
1. Know the company or sender of the email. Research if needed.
2. If you know the sender, but it still looks suspicious, check with them.
3. If you think it is a scam, report it to the FBI Internet Crime Complaint Center.
4. Protect yourself with a spam filter and MalwareBytes.
