Why Do We Need Anti-Spam Software?
Spam,​ otherwise known as​ junk email or​ unsolicited commercial email; is​ quickly becoming on​ of​ the​ most prevalent complaints of​ internet users .​
Not only is​ it​ annoying,​ but it​ is​ quickly becoming a​ dangerous and potentially expensive problem for businesses as​ well as​ individuals.
How is​ it​ dangerous?
First and foremost,​ spam is​ one of​ the​ leading causes for clogged networks and slow connections .​
American Online,​ one of​ the​ nation’s largest internet service providers; transmits over 8 trillion spam email messages a​ year .​
Those messages tie up valuable bandwidth and can slow down entire networks .​
Although end users will rarely see a​ significant change in​ their connections,​ they can rest assured that a​ noteworthy portion of​ their monthly bill is​ paying for that lost bandwidth.
Most spam includes images or​ weblinks within it​ commercial content .​
Although some of​ it​ is​ begin or​ at​ worst annoying,​ an​ increasing portion contains sexually explicit content .​
Spam messages frequently contain pоrnographic pictures or​ links to​ sex-related websites.
These messages are not suited for children yet can easily be accidentally opened by minors .​
In addition to​ simple sexual content,​ some of​ the​ most severely sexually explicit spam can contain images of​ such illegal and offensive acts such as​ bestiality or​ child pоrnography.
Aside from slowing connections or​ carrying unwanted pоrnography,​ spam is​ the​ leading cause of​ transmitted computer viruses .​
Computer viruses are programs which run malicious code which can damage computer systems,​ delete files and steal personal information .​
These viruses are often hidden in​ an​ email messages as​ attachments such as​ a​ pictures .​
Email transmitted viruses can render entire systems inoperable and delete important documents forever.
How can you​ stop it?
The easiest and most simple way to​ stop unwanted email is​ to​ employ a​ spam blocker .​
Spam blockers are manufactured by a​ variety of​ companies and be anywhere from free to​ costing upwards of​ 50$.
There are three basic types of​ spam blocking software .​
The first is​ a​ key-word blocker .​
These programs examine the​ header and body of​ an​ email message looking for a​ series of​ predefined criteria .​
For example,​ a​ program could be instructed to​ flag or​ block any email message containing the​ word sex.
Although seemingly straightforward,​ the​ spam blocker also has to​ stop any spelling variation of​ sex such as​ sexx or​ s_e_x .​
Although this type of​ spam blocker can do very well at​ stopping spam,​ it​ also has a​ tendency to​ block personal emails which may or​ may not contain flagged words.
The second type of​ spam blocker is​ an​ address list blocker which blocks or​ flags any emails not coming from a​ predefined list of​ addresses (such as​ the​ user’s address book).
Although this type of​ spam blocker does a​ very good job of​ not blocking personal emails from friends or​ family,​ it​ can inadvertently delete important messages from users not on​ the​ original predefined list .​
This can make it​ very easy to​ miss potentially important yet unexpected emails.
The third type of​ spam blocker is​ actually a​ hybrid of​ the​ aforementioned varieties .​
It will filter emails from known friendly accounts directly to​ the​ inbox while holding potentially dangerous emails in​ the​ filter .​
The user can then go in​ and sort through emails from either friendly strangers (non spam emails from unfamiliar addresses) or​ unfriendly strangers (spam emails from unfamiliar addresses).
Although these programs do require a​ slight amount of​ user interaction,​ they can protect your computer and keep you​ from inadvertently deleting important emails.
