'Every person on the net has one thing in common. They all hate spam'. This sentence opens a recent BBC article announcing 2002's top ten unwanted emails (a phenomenon referred to as 'spam') and accurately conveys how most Internet users feel about the thousands of unsolicited messages that continually flood their inbox.
The 'Top Ten' list was compiled in Great Britain by the company Surf Control. And many of these spam items are all familiar to net users from our country. Who hasn't got one of those messages titled 'Free adult site passwords', 'Viagra Online', 'Refinance your mortgage' or 'Best online casino'? And so, it's no shock to see these on the list. Because it's a British list, the most annoying spam messages from our country are not featured, as happens with the one selected by the VilaWeb editorial staff as the year's most important: How to pronounce 'Euro' in Catalan. The volume of unwanted messages is reaching daunting proportions. Just one example: in a study made public last September, the company Jupiter Research estimated that some 140,000 million spam messages are sent per year – a figure that will reach 650,000 by 2007 if something isn’t done.
 
The Battle Against Spam
+ The battle against spam has been recently gathering force.
The battle against spam has been recently gathering force. Spearheaded by North-American groups until recently, the resistance movement has now spread to other countries. In France, for example, the protection of internet users privacy has been taken on by CASspam. In addition to advice and basic guidelines for avoiding bulk mail, the company also offers Website managers software applications that prevent the email addresses included on their web pages from being incorporated into databases compiled by 'spammers'. Microsoft has recently joined the effort to tackle the problem. To keep massive amounts of spam from collapsing the inboxes of Hotmail users, the company has signed a contract with Brightmail, which promises that it is able to block 90% of all spam. Yet so far, despite all efforts, the battle is far from being won.
Computer Viruses
+ If there's anything more annoying for Internet users than spam, it's viruses.
If there's anything more annoying for Internet users than spam, it's viruses, which in some cases, can delete all a computer's data. In recent years, the SirCam, Melissa and I loveyou viruses have wreaked Web havoc. But possibly the virus with the greatest potential for destruction is Klez, which emerged in December, 2001 and has caused an enormous amount of damage. It's estimated than one out of every 300 messages circulating on the net is infected with some variation of Klez. McAfee, Symantec, Wired and Quands all provide good information on their websites for how to remove the virus.
'Hackers'
+ Each day countless attacks against websites are being carried out by hackers
While most of us carry on about our business, each day countless attacks against websites are being carried out by hackers (a term coming from the word 'hack', meaning to cut into). Most of such visits result in modifications to homepage content with the insertion of sarcastic images or text that contradict the website's editorial line. Drawn by the expertise these hackers have amassed in their boycott of the Web, many companies are hiring their services to protect their own webpages against attacks. In our country, there are many hacker websites, ranging the gamut from Artefacte.org and Xàpers. It could be said that hacking is destined to be institutionalised: hacker activity has reached such a level that last December the Kernel Panic HackLab offered a course on the history of hackers.
