E-mail virus scan
Learn about viruses which spread through e-mails and methods for blocking them
An e-mail virus is a code sent to the user as an e-mail note attachment when activated. It can cause some unexpected and highly harmful effects such as destroying some files on the hard disk, and causing the re-mailing of that attachment to everyone in the address book. Just like other kinds of computer viruses, e-mail viruses can also cause severe loss of time and money. These viruses can spread in many ways. They may be sent as an executable file in an e-mail attachment and can trick the recipient into clicking on it. On running these attachments, the recipient gets affected by it. Some viruses can be sent as an HTML based e-mail with code in it designed to take advantage of vulnerability in the browser or the e-mail client to install itself onto the targeted computer system.

Benefits of scanning e-mails for viruses
To protect computers from these e-mail viruses, an effective security software can be used. E-mail virus scan uses artificial intelligence to scan e-mails and can identify about 80% of the new and malicious codes. They replace threatening code and infected attachments with a text file informing the user about the problem. E-mail virus scans are more reliable as the e-mails are scanned automatically to detect and block new viruses so that the user can get fast and reliable protection.
Installing e-mail virus scanning software
Many e-mail virus scanning software are available, for instance, say a mail scanner. It is an e-mail security and antispam package for e-mail gateway systems. It is designed to run on mail servers operated by companies and Internet service providers so that all their users and customers can be protected from a single place. This avoids the need for installing software on individual PCs. Likewise much other software is available which can be downloaded from internet and can be installed on the PC. Just downloading and installing the software cannot help much, instead upgrading these software is also vital.
Ways to scan the viruses
An important way to keep the system free of viruses is by the use of antivirus software. They scan files regularly to make sure that the computer is free from viruses. They also scan the e-mail attachment before it gets downloaded to the computer. The antivirus software should be configured to boot automatically on start up and run at all times. This can help to provide backup protection even if the user forgets to scan an attachment. Antivirus software should be updated at regular intervals. It is only as good as the frequency with which it is updated.
