Spam Protection - Know Thy Enemy: Viruses and Malware, Trojans and Adware

It has become increasingly common for spam to contain malicious programs or software that can be harmful to both your computer. The purpose of these small, malicious is to perform unauthorized, usually harmful, actions, when they self-install into your computer system, and infect your programs and files. They are commonly spread by e-mail, in the form of cleverly disguised attachments that trick you into clicking on them.

The most common of these programs are: Viruses, Trojan Horses, Malware and Adware. Knowing what they are and how they work will help you better protect yourself from malicious spam.

Viruses

A is a computer program that is specifically created to replicate itself and to infect a computer system without permission or even knowledge of the user. Viruses come in several varieties including:

The Boot Sector Virus

This virus will infect the root-most part of your computer hard drive, called the boot sector. This is what is used to start up your computer.

This type virus can prevent your computer from starting and may even force a hard drive format, causing you to lose all of the information on your computer in one fell swoop.

The Program Virus

This is an executable file. It becomes active when the program it has infected is run. When it is activated, it will infect other programs on your hard drive, disabling them.

The Macro Virus

The third type of virus specifically targets documents such as Microsoft word. It is activated when the infected document it has infected is run. One action it may perform, for example, is to erase dates in your documents as well as other areas of the computer.

Malware

The term "malware" is short for malicious software. It is a type of program that propagates on your hard drive and can create untold problems when it does so. Malware may install a program that you did not want, or ask for. When it does so, it will use up many of your computer's system resources, effectively slowing it to a near standstill.

Trojan Horse

Much like its Greek namesake, the Trojan horse program is a seemingly harmless and innocuous application or file, but it contains harmful, malicious code and, when installed, can wreak havoc on your computer system. This program often runs undetected, giving the hacker access to your computer system and, for example, your personal information such as saved passwords and bank account numbers. The hacker is also able to display messages on your computer screen.

Adware

While not necessarily malware, but adware can be used for malicious purposes. Adware goes above and beyond what is reasonable advertising. It is adware, in fact what has given a bad name to some otherwise incredible free software that may actually be very beneficial to you.

It generates popups or other annoying advertising that can in fact freeze or lock your computer. In many cases, the adware is difficult if not impossible for the regular user to remove, disable or even detect.

In addition to displaying ads for the original advertiser, adware may log your whereabouts on the internet and send user information back to the spammy ad company about your computer use without asking for your permission to do so.

Spam is not always the most harmful thing you will find in your inbox; it is the attachments that come with spam that can really devastate your computer system. It is crucial that you do not open attachments in unsolicited email.

The volume of spam that is sent out every minute of the day has reached pandemic proportions. The simple reason for this is because the cost to a spammer ranges from zero to negligible. In fact, anyone with a list of email addresses and Internet access can spam thousands, even millions of people with a single click of the mouse. The cost of spam, however, now runs in the millions.

Bandwidth

Spam takes up valuable Internet bandwidth that would otherwise be used for legitimate business and personal use. Bandwidth refers to rate at which data is transmitted; it is the amount of data that can be transmitted within a fixed amount of time. The lower the bandwidth, the slower the transmission.

When spam uses up valuable bandwidth, and clogs up the system, it causes costly delays in the transmission of important, legitimate information. It forces the Internet Service Providers (ISPs) to increase bandwidth just to handle the increased volume. This costs money, and this cost is passed on to the consumer.

Viruses, Worms and Malware

It is becoming an increasingly common menace. Spammers will attach viruses to the email they send out for purely criminal or malicious purposes. Some viruses, for example, are programmed to self-install and give the spammer access to all the vital information stored on your computer. This information is often be used for identity theft purposes.

Other viruses simply do great harm to computers the world over. A Consuner Reports study estimates that the cost of repairs and replacement parts for damage done to computer systems by viruses was over 8 billion over the past two years. This does ot take into account the billions spent on anti-spam and anti-virus software.

Productivity

Spam is not only annoying, it also takes up valuable time just to go through it and figure out sort out the spam from the valid mail. For businesses that receives hundreds of emails a day, the cost in time and productivity really adds up.

The "cost of spam calculator" that is available at cmsconnect.com estimates the that spam costs almost $1000 per employee each year, with over 50 hours of lost productivity for each one.

Lost Messages and Data

As we try to battle the spammers by installing spam filters and blockers, these programs often weed out legitimate businesss correspondence. Lost correspondence from a client or supplier can easily cost businesses money, clients and goodwill

Identity Theft

The phenomenon of phishing has become more prevalent as spammers think up new ways to make a buck at your expense. Phishing involves the use of email that is designed to look like a legitimate company has sent it. It is sent out to millions of people in the hope of scamming them into revealing personal information that the scammer can use for identity theft. The cost of Phishing and identity theft to their victims now also runs in the billions.

The cost of spam is a financial drain on the economy. We pay a high price for the spammer to scam his victims. The spammer pays nothing. Search
