The most dangerous email viruses
Email viruses are malicious software that infects a computer by attaching itself to an email message and replicating itself when the message is sent to other email addresses. Email viruses are typically spread by sending infected email attachments or by clicking on links in infected email messages.
Email viruses can cause a number of different problems, including deleting files, stealing information, and sending spam. Some email viruses can also spread to other computers on the same network, making them particularly destructive and difficult to contain.
The most dangerous email viruses are typically those that are able to replicate themselves and spread quickly. Some of the most dangerous email viruses in recent years include the MyDoom virus, which caused billions of dollars in damage, and the WannaCry virus, which encrypted files on infected computers and demanded a ransom for the decryption key.
Fortunately, there are steps that users can take to protect themselves from email viruses, including using antivirus software and being cautious when opening email attachments or clicking on links in email messages.
