Antivirus - Email Protection Nowadays, most viruses are spread in the form of e-mail attachments. This is because some of the worst recent viruses relay on recipients that throw away common sense and launch a deadly e-mail attachment. Commonly the attachments are with extensions that include .bat, .com, .exe, .pif, .scr, and .vbs. Sometimes to avoid the filters of antivirus software, virus creators enclose their malicious code in a .zip or .rar archive file. The file might even have a password to full antivirus programs that scan inside archives. Also, make sure your e-mail software is configured so it will not automatically open attachments.

How Antivirus Software works

Antivirus software is essential on any computer that is connected to the internet or has multiple users who use floppies or other removable media on a regular basis. While most decent antivirus software is not really all that complicated, it certainly can’t hurt to have a clearer understanding of how they work, and what they do for you behind the scenes to keep your PC clean and safe.

Antivirus software works by checking files, programs, emails and disks for viruses, worms and Trojans, and more recently, spyware. What it is actually doing is comparing what it finds with a list of known viruses – this list is a virus file or virus definitions file. The software will unpack files to look at and check them, and it then repacks them if they are safe. If the files contain viruses they will be destroyed or placed in a quarantine zone. Most antivirus software will also attempt to repair any files that have been damaged by a virus.
