The security of computers connected to the Internet remains a problem. Despite the efforts of major Anti-malware companies, a high proportion of computer infections remain undetected, Internet crime continues to grow and new malware is being discovered at the rate of many tens of thousands of items per day. The situation is getting worse, proving that existing security technologies, whilst useful, are inadequate.
Even if you have a properly configured Firewall, an updated and frequently used Anti-Virus, practice safe surfing, never open attachments or click unfamiliar links, you will still likely become infected. Why? Because Anti-virus and Anti-spyware scanners are not able to cope with the enormous volume of new malware; estimated by recent surveys to be more than 30,000 new items appearing each day.
