In the meantime, victims may lose job opportunities, be refused loans, education, housing or cars, or even get arrested for crimes they didn't commit. This contact may be made through a telephone call or a faxed request. If you receive a telephone call or a fax from someone claiming to be with the IRS and you are not comfortable providing the information, you should contact our customer service line at to verify the validity of the call or fax.
You may then contact the IRS employee who requested the information and provide the required information. The scams may take place through e-mail, fax or phone.

The majority of computer viruses are email viruses, making an effective email security strategy critical in protecting your business from viruses, malware, and other malicious threats.
With the rapid evolution of email attacks such as zero-day exploits and ransomware, traditional antivirus software is insufficient in protecting users against dangerous and costly attacks. In order to provide effective email protection, this technology must be implemented as part of a proactive, fully supported cloud email security solution that provides comprehensive, real-time email vigilance.
Email viruses , which constitute the majority of computer viruses, consists of malicious code that is distributed in email messages, and can be activated when a user clicks on a link in an email message, downloads an email attachment or interacts in some other way with the body of an infected email.
Virus emails are usually programmed to be sent to everyone in the victim's address book once his or her computer has been infected, and tend to proliferate very quickly as a result.
Viruses are commonly linked to phishing attacks, in which threat actors send out fraudulent emails from spoofed or compromised accounts that appear as if they have been sent from authorized sources with the goal of tricking users into sharing sensitive information. These attacks often leverage stealthy social engineering techniques to manipulate psychology and deceive victims.
Spam, ransomware, business email compromise BEC , whaling and ransomware are among other attacks that are notorious for infecting systems and compromising networks with email viruses.
Viruses can be included as an attachment in a malicious email, or in the body of the email itself. Some viruses capitalize on nothing but user naivety. Have you ever forwarded a chain letter, a virus warning or a desperate plea for help? If so, you probably fell for a hoax and helped to spread a virus.
In these scenarios, the virus is the email itself. Collectively, these emails clog up mail servers and inboxes and frequently result in denying service to legitimate users while the system processes these bulk messages.
There are many different forms of email viruses, and new zero-day viruses are rapidly emerging, making securing email in this modern digital threat environment even more complex. Some types of email viruses are more dangerous than others. A few of the most threatening types of email viruses include:. Polymorphic viruses are those which have code in them that changes how they operate, thus defeating detection by normal methods.
These complex and especially dangerous viruses employ various tactics to modify themselves during each infection. They vary their physical file makeup by encrypting their codes and using different encryption keys generated by mutation engines each time that they infect a device. This technique allows the majority of polymorphic viruses to remain undetected by antivirus software which is engineered to recognize a static, unchanging code. Polymorphic viruses are usually spread via spam email, malware or infected websites.
VIRLOCK, one of the most notorious polymorphic viruses, evolved to combine file infection and ransomware, making it especially difficult to detect and remove. As computer viruses have become increasingly problematic, methods of detection have evolved to combat them. There are several different methods that antivirus programs employ to identify viruses, malware and other computer threats.
These methods include:.
