Symantec says it now finds as many as 8,000 pieces of malware a day, and that security threats have increased over the past 18 months. Speaking at Gitex, the company, which recently launched Internet Security Suite 2009, said not all will pose a danger to users, because of the range of languages such threats come in. Symantec said it has changed the way it tackles security threats, issuing customers with new anti-virus definitions every few minutes.
