First, ''a_nahuche'' was using a very popular Internet shorthand and the jest of his statement was, ''You Can't Be Sure Virus Companies Are Not Writing Viruses to Keep Them in Business''. Which is true!
Don't criticize a poster because you don't understand their writing style. Many of us wonder why you mis-spelled ''Offense'' with a ''c''! But a more foreign language aware person would realize you are most likely a Brit (or a derivitive there of). Excuse me, but because his post wasn't in proper British English, is no reason to burn him for his post.
Now my two American cents worth, in good ''Ole American English'' on this subject.
It is common knowledge that ''Bill Gates wrote the first code ''virus'' to break a program, in high school (yes it was probably an accident, but he learned from it. hee hee). Thus ''Computer Viruses'' were born. He was also known as the ''Mother Of All Hackers (MOAH)'' from when he exploited (Hacked, Stole same thing) the ''Basic'' OS running on Harvard's Mainframe computer and ported it to the ''Altair 8800'' that started him on his way to his billions of dollars.
It is now widely known that he duped his friend out of a hacked copy of QDOS (aptly named ''Quick n Dirty Operating System'') then renamed it various other names according to who it was being sold to. IBM PC-DOS, COMPAC-DOS, MS-DOS, etc. etc. Gates was fond of hiring young high school and college kids as code slaves for further writing of the OS. Bored, underpaid, overworked, mischievous, they began putting ''bugs'' in the code. Hence we still have Microsoft computer ''bugs'' today. Were they put there on purpose with Bill's knowledge? Probably as was the case with COMPAQ-DOS. Bill loved it when his company got paid more money the next year to write a fix. Thus building in code to break, was born.
Much like many shipyard workers in the past(and their bosses), were known to set logs afloat in the river channels of the old days. They called them ''Silent Messengers''! But they only used this practice when business was slow and - or they were about to lose their jobs. Does this justify it? No! You ever heard of the disgruntled ''Postal Employee'' going postal? The same thing happens in every business. Many of the ''bugs'' are just another form of ''Silent Messengers'' of today. Hey anything to make a buck, right?
I'm not saying that everyone who works for a Corporation is a bad person, but greed can do strange things to employees and the powers that be in the Corporate Machinery, as has been proved countless times in history. A prime example comes to mind in the ''Enron'' fiasco. Countless people and it's own employees life's were destroyed for the benefit of a few dishonest, greedy, executives!
Many posters here, have taken an affront to the negative comments of distrust for the software business world (anti-virus program writers are just one of them). Have they forgotten companies like ''Enron''? Who will the next ''Enron'' be? Will it be Symantec (Norton Anti-Virus, etc) or will they just succeed in getting away with letting viruses slide through till next year, to prolong our agony, increase the Bosses profits and promote job security. After all Microsoft got off Scot free on 90% of their underhanded tactics over the last 25+ years (stealing code and profiting from it has become an art form for them). Many here are just plain too naive to take an honest look at the slithering underworld of corporate dealings going on everyday in Life.
To ignorantly believe that it is not possible, is like turning a blind eye to the ''Anything Goes'' marketing and business tools used to rob us blind and smoke-screen (Tobacco Industry) us to death. Literally! With information and knowledge of history, we may just survive in this ''The Ball Always Rolls Downhill'' world and in the end it becomes not so amazing on how many people are willing to turn their head, if it involves earning a few almighty dollars. Suspicions are indeed justified and may help us survive. Sony has just recently proved how right we are to be wary and distrusting of the Corporate World. Root Kits are about as close as it gets to proving my Point and making hogwash of the viewpoint that Corporate Citizens are Saints!
As the French say ''C'est La Vie'' (such is life), ''C'est La Guerre'' ( such is war)!
