Titolo: Perché SPAM ?

Ciao a tutti
ho installato AVG 7.5.
Quando ricevo le e-mail nell'oggetto viene indicato "SPAM" racchiuso tra due 
parentesi quadre prima del titolo dell'oggetto. Ritengo che ciň sia dovuto 
al controllo di AVG, ma cosa significa esattamente questa segnalazione?
Grazie a chi risponderŕ e salute a tutti

Che le email ricevute sono considerate pubblicita' non richiesta da AVG, se
lo fa con tutte le email probabilmente devi 'educare' AVG insegnandogli
quali siano gli indirizzi non SPAM.

Qui sotto hai una "spiegazione" (in Inglese) del fenomeno SPAM.
Ciao,

SPAM:
E-mail that is not requested. Also known as "unsolicited commercial e-mail" 
(UCE), "unsolicited bulk e-mail" (UBE), "gray mail" and just plain "junk 
mail," the term is both a noun (the e-mail message) and a verb (to send it). 
Spam is used to advertise products or to broadcast some political or social 
commentary.
A Social Plague
Like viruses, spam has become a scourge on the Internet as hundreds of 
millions of unwanted messages are transmitted daily to almost every e-mail 
recipient as well as to newsgroups. Unfortunately for users and fortunately 
for spammers, as an advertising medium, spam does produce results. Even if 
only an infinitesimal number of users reply, it is still cost effective 
since e-mail is a very inexpensive way to reach people.
ISPs Work Overtime
In order to alleviate some spam, ISPs have added an enormous number of 
servers doing nothing more than spam filtering (see spam filter). The 
CAN-SPAM act in the U.S. became law on January 1, 2004, which provides 
severe penalties for spammers, if they can be located (see CAN-SPAM). See 
spim, mail bomb, Joe Job, SPF, letter bomb, spamdexing, Blacklist of 
Internet Advertisers, munging, RBL, ROKSO, MAPS, spam relay, spam trap, 
botnet, rogue site and opt-in.
Why Do They Do It?
Simple math. Suppose that out of 2,000 spam messages, one person clicks the 
link, and the spammer makes $1. If a million spams were sent that day, the 
spammer made $500, and the job might have taken a half hour to set up. That 
means only a few hours per week could yield $100,000 a year. Is that 
incentive enough for high-school students, or would they rather go back to 
their paper routes? Of course, consistent revenues are not guaranteed, but 
some spammers make a whole lot more than $100,000 every year. In any case, 
there is ample motivation.
Spam Filters Create More Spam
As spam filtering becomes more sophisticated, spammers have to send even 
more spam to make the same money, but e-mail lists can be purchased for very 
little or hijacked. There is a thriving business selling e-mail lists to 
spammers as well as lists of compromised computers (see zombie). There are 
even third-party spam service providers that will do all the work for you.
Easy to Rationalize
Spammers justify their existence by citing the enormous amount of 
unsolicited ads we get via the postal system, which wastes trees and other 
resources. They claim advertisers pollute the environment every day with 
obnoxious ads on TV, radio, buses and billboards. Of course, they have a 
point, especially regarding the tons of paper thrown in the "real" trash can 
every day. However, none of these other approaches threaten to close down 
the system they live in.
