Securing Business Emails Against Email Viruses
Email viruses, which account for the majority of computer viruses, can compromise sensitive data, harm hardware and waste critical resources. User-downloaded viruses are responsible for 2,000,000 to 5,000,000 attacks per day.
What Is an Email viruses?
Email viruses are commonly linked to phishing attacks, and many rely on user naivety to infect devices and spread. Others are hidden in stealthy social engineering attacks and employ advanced techniques like masquerading as a seemingly harmless file by changing their signature, making these viruses highly difficult to detect and avoid.
Types of Securing Business Emails Against Email Viruses
There are many different types of email viruses, and new zero-day viruses are rapidly emerging.
A few of the most dangerous types of email viruses include:
Boot Sector Viruses
These viruses spread on the master boot record, making them very difficult to remove and frequently resulting in a full system reformat.
Direct Action Viruses
When a user clicks on a file infected with a direct action virus, the attached virus is activated and continues to spread.
Resident Viruses
This type of virus infects files, installs itself on a PC and can persist even after the primary source of the virus is removed.
Multipart Viruses
These viruses can infect the boot sector as well as files on a computer and can spread extremely rapidly and be very difficult to remove.
Keyloggers
When installed on a device, this type of spyware enables a malicious actor to track and log the keys that the user strikes on his or her keyboard, capturing sensitive information that is typed without the user's knowledge.
Polymorphic viruses
This type of virus changes its signature when it reproduces, masquerading as a different and seemingly harmless file.

Safeguards the Inbox against Zero-Day & Polymorphic Viruses
Regardless of the techniques that it utilizes to detect viruses and other threats, antivirus software has its limitations. Antivirus programs are often ineffective in detecting zero-day and polymorphic viruses, and virus designers test new viruses that they create on established antivirus applications to ensure that they are not detected before releasing these viruses into the wild.
Guardian Digital keeps even the most sophisticated and stealthy email viruses out of the inbox with a combination of multi-layered detection engines powered by heuristics and advanced email filtering technologies capable of detecting and blocking all types of email viruses.
