The most common types of electronic infections:
|
• Virus - a program or code that replicates itself and infects another program, boot sector, partition sector, or document that supports macros, by inserting itself or attaching itself to that medium. Computer viruses are often attached to other software or documents you might receive. When you run the virus's software or the file the virus has infected, the virus can infect your computer's software. Many computer viruses are malicious - they can erase your files or lock up whole computer systems. Other computer viruses are more benign - they don't do any direct damage other than by spreading themselves locally or throughout the Internet.
• Worm - a program that resides in the active memory of a computer and duplicates itself; for example, from one disk drive to another, or by copying itself using email or another transport mechanism. Once the worm has infected your system, it may automatically send out emails containing more copies of the virus using the address book in your email program. The worm may do damage and compromise the security of the computer. It may arrive in the form of a joke program or software of some sort. Unlike a virus, it does not attach itself to a host program.
• Trojan horse - a malicious program that pretends to be a benign application; a Trojan horse program purposefully does something the user does not expect. Trojans are closely related to computer viruses, but they are not viruses since they do not replicate, but Trojan horse programs can be just as destructive. Many people use the term to refer only to non-replicating malicious programs, thus making a distinction between Trojans and viruses.

Virus protection
|
Half a dozen new viruses are created every day with the sole purpose of causing havoc on your PC. The best line of defense is a powerful anti-virus utility designed to stop damage to your computer from multiple sources such as web surfing, e-mail and rouge programs. You also need anti-virus software, which blocks malignant files from reaching your computer via email attachments, documents, or executable programs. Firewalls don't scan incoming emails or email attachments. Some firewall software programs come with a "suite" of security, including ad blocking, spam filtering, and, of course, anti-virus protection. If your firewall software includes anti-virus software, then you don't need to purchase additional anti-virus protection.

Question of the Day
• What are cookies and how do they work?
A cookie is a piece of data which often includes an unique identifier, that is sent to your browser from a web site you visit, stores as a file on your computer, identifies you as a unique user and track your web usage. There are two commonly known types of cookies. One is called a "session" or "non-persistent cookie." It is a cookie that only exists as long as your session on the web site lasts and expires as soon as you leave the web site. It is used to facilitate your activities within that site. The second type of cookie is a "persistent cookie". It exists beyond the life of your session and may live for months or years. A persistent cookie is created in order to recognize users when they return to a website. It enables the site to offer a customized experience tailored to that user - such as remembering your name and password on protected login pages. Cookie data is stored on the user's hard drive. The filename is different for each platform. For example, on Windows machines, cookie data is stored in *.txt files. A web site may set an expiration date for a cookie it delivers. If no expiration date is specified, the cookie is deleted when the user closes the browser.
