Email Security - Don't Let Them Trick You

 

Every day, thousands of people are fooled by email from criminals trying to steal their identities or infect and take over their computers (Harmful Email Subjects to Avoid). This article will help you avoid being a victim. The attacks listed here are the tip of the iceberg. Never open email attachments from people you don't know, and be very careful even if you do know the person; especially if you aren't expecting an attachment.  Also, don't click on links in emails unless you can guarantee the email came from someone who is not trying to fool you. It is usually our curiosity and impatience that assists new worms to propagate around the internet.  Again, programs like Panda Antivirus, Kaspersky Anti-Virus and  ZoneAlarm Pro 5.0 provide a very good level of protection against email worms (again, please make sure virus signatures are automatically updated as frequently as the program allows).
